The Sons of the Pioneers are one of the United States' earliest Western singing groups.^[1] Known for their vocal performances, their musicianship, and their songwriting,^[2] they produced innovative recordings that have inspired many Western music performers and remained popular through the years.^[3] Since 1933, through many changes in membership, the Sons of the Pioneers have remained one of the longest-surviving country music vocal groups.^[4]

In the spring of 1931, Ohio-born Leonard Slye, the cowboy singer who would later change his name to Roy Rogers, arrived in California and found work as a truck driver, and later as a fruit picker for the Del Monte company in California's Central Valley. He entered an amateur singing contest on a Los Angeles radio show called Midnight Frolics and a few days later got an invitation to join a group called the Rocky Mountaineers.^[5]

In September 1931, Canadian-born Bob Nolan answered a classified ad in the Los Angeles Herald-Examiner that read, "Yodeler for old-time act, to travel. Tenor preferred." The band was The Rocky Mountaineers, by then led by Leonard Slye. After listening to the tall, slender, tanned Nolan sing and yodel, Slye hired Nolan on the spot. Although Nolan stayed with the group only a short time, he stayed in touch with Slye. Nolan was replaced by Tim Spencer, who had been working in a Safeway Stores warehouse.^[4]

In the spring of 1932, Slye, Spencer, and another singer, Slumber Nichols, left the Rocky Mountaineers to form a trio, which soon failed. Throughout most of 1932, Slye and Spencer moved through a series of short-lived groups like the International Cowboys and the O-Bar-O Cowboys. Spencer left the O-Bar-O Cowboys and quit music for a while. Slye joined Jack LeFevre and His Texas Outlaws, who were a popular act on a local Los Angeles radio station.^[6]

In early 1933, Slye, Nolan, and Spencer formed a group called the Pioneer Trio. The three young singers rehearsed for weeks honing their singing. While Slye continued to work with his radio singing group, Spencer and Nolan began writing songs for the group.^[4]

By early 1934, the group consisted of Leonard Slye, Bob Nolan, and Tim Spencer on vocals, with Nolan playing string bass and Slye playing rhythm guitar. During that time, fiddle player Hugh Farr joined the group, adding a bass voice to the group's vocal arrangements. He also sang lead on some songs. Later that year, the "Pioneers Trio" became the "Sons of the Pioneers" through a radio station announcer's chance remark. Asked why he'd changed their name, the announcer said they were too young to have been pioneers, but that they could be sons of pioneers. The name was received well and fit the group, who were no longer a trio.^[4]

By the summer of 1934, the Sons of the Pioneers' popularity and fame extended beyond the Los Angeles area and quickly spread across the United States through short syndicated radio segments that were rebroadcast all over the country. They signed a recording contract with the newly founded Decca label, and on August 8, 1934, the Sons of the Pioneers made their first commercial recording. That same day, the immensely popular crooner Bing Crosby also made his first Decca session.^[4]

One of the first songs recorded by the Sons of the Pioneers during that first August session was written by Bob Nolan, "Tumbling Tumbleweeds", that would soon become a staple in their repertoire. The original title "Tumbling Leaves"^[7] was changed to give the song a western character. Over the next two years the group would record 32 songs for Decca.^[8] Their output includes a 1937 recording of "The Blue Juniata," by Marion Dix Sullivan.

Between 1935 and 1984, the Sons of the Pioneers appeared in 87 films, several short films, and a television series.^[9] In 1935 they signed with Columbia Pictures to supply the music for the studio's Charles Starrett westerns. In 1937, Leonard Slye was offered a contract as an actor with rival Republic Pictures. Part of that deal required him to leave the singing group. Leonard Slye was rechristened Roy Rogers, and went on to achieve major success as a singing cowboy in the movies. Roy Rogers and the Sons of the Pioneers remained close throughout the coming years. When the Starrett unit disbanded temporarily at the end of the 1941 season, the Pioneers rejoined Rogers at Republic and were soon appearing as highly popular supporting players in the Rogers westerns.^[10]

By this time the group was billed as "Bob Nolan and the Sons of the Pioneers." Nolan was reluctant to be the "leader" of the group, which had been formed as a co-operative outfit with no formal leader, but he bowed to the demands of show business. Agents, music publishers, and recording companies insisted that co-operative bands needed a name to promote them (as in Glen Gray and the Casa Loma Orchestra). Because Bob Nolan's featured appearances with Starrett had made him the most recognizable of the Pioneers, Nolan reluctantly became the "front" for the group. The group, as "Bob Nolan and the Sons of the Pioneers," made guest appearances in the Warner Bros. all-star revue Hollywood Canteen (1944, singing "Tumbling Tumbleweeds") and the RKO Hollywood-themed comedy Ding Dong Williams (1945, singing "Cool Water").

The Sons of the Pioneers always valued radio exposure, and appeared often on radio broadcasts. They had three network shows of their own: 10-2-4 Ranch (1941-45, for Dr Pepper), Radio Rodeo (for the Mutual Broadcasting System, 1941-42), and The Lucky U Ranch (1951-53, for Planters Peanuts).

The group also began making transcription records for broadcast in 1934. These were syndicated by Standard Transcriptions (1934-36), Mutual (1939, as The Sunshine Ranch), RCA (1940, as Symphonies of the Sage), the Armed Forces Radio Service (1942-45, as Melody Roundup), and Teleways (1947-49, as The Sons of the Pioneers Show).

The Teleways series was intended as a daily 15-minute show but could be programmed anywhere on a station's schedule, at the station's discretion. The group prepared a demonstration record for radio stations and their potential local sponsors, with announcer Art Gilmore reading promotional copy between songs. The informal, semi-scripted show had Bob Nolan acting as master of ceremonies, bantering with the other singers between numbers. The group was careful to program a variety of choral music, including cowboy songs, barbershop harmony, sentimental ballads, and spirituals, to appeal to the widest possible audience. The personnel were Bob Nolan, Tim Spencer, Lloyd Perryman, Pat Brady, Hugh "Foghorn" Farr, Karl Farr, and Ken Carson. The earliest shows include studio musician Ivan Ditmars accompanying them on piano and organ; Nolan appreciated Ditmars's efforts but preferred that the group's established sound should be preserved for the radio series, so Ditmars was released. Toward the end of the run, as an economic measure saving both time and money, the later Teleways shows were patched together from previous programs (including some songs with Ditmars), with new spoken dialogue by Nolan and the gang connecting the older performances.

Republic Pictures president Herbert Yates released the Sons of the Pioneers from their movie contract in 1948, replacing them with a less expensive alternative, Foy Willing's Riders of the Purple Sage. The hurried nature of the Sons of the Pioneers' last radio shows reflected Tim Spencer's and Bob Nolan's anxiousness to move on; both left the group in 1949, after their radio commitments had been fulfilled. Tim Spencer retired from performing with the group, to devote himself to handling the group's business interests; his place in the group was taken by singer Ken Curtis. Bob Nolan was replaced by Tommy Doss, who sounded almost exactly like him. Lloyd Perryman took over Nolan's emcee duties. Nolan returned to the group in 1955 at the insistence of RCA Victor, which valued the group's distinctive sound with Nolan, and refused to record the Sons of the Pioneers unless Nolan was present. Nolan's participation was limited to RCA records through 1958; he no longer appeared with the group. Similarly, Tim Spencer still participated in the RCA recording sessions through 1957. Hugh Farr retired from the group in 1959 and his brother, guitarist Karl Farr, died in 1961. The group continued to record new albums for RCA through the 1960s, the last being a collection of Hawaiian songs, The Sons of the Pioneers Visit the South Seas (1969).

In 1971, Bob Nolan and Tim Spencer were both elected to the Nashville Songwriters Hall of Fame. In 1972, most of the surviving members of the Sons of the Pioneers, including the original Pioneer Trio of Roy Rogers, Bob Nolan, and Tim Spencer, gathered at the Ambassador Hotel in Los Angeles for one last performance.

The late 1970s saw the passing of the founding members of the group. Tim Spencer died on April 26, 1976. Lloyd Perryman, who had been with the group since 1936, died on May 31, 1977. Hugh Farr, who had retired from the group in 1958, died on April 17, 1980.

In 1979, Bob Nolan returned to the studio for the final time and recorded a successful solo album of classics and newer compositions titled Bob Nolan – The Sound of a Pioneer. Nolan died on June 16, 1980. That same year, the Sons of the Pioneers were inducted into the Country Music Hall of Fame.

The Sons of the Pioneers have never stopped performing since their inception in 1934. Following the death of Lloyd Perryman in 1977, Dale Warren, who had joined the group in 1952, took over the leadership of the Sons of the Pioneers, guiding them into the 2000s until his death on August 8, 2008. They continued to perform in concert and recorded as well, with a lineup that featured, among many others, Luther Nallie (guitar, vocals), Rusty Richards (vocals), Billy Armstrong (fiddle), Billy Liebert (accordion), Gary LeMaster (lead guitar), Rome Johnson (vocals),^[4] and Roy ("Dusty") Rogers, Jr. (vocals, MC), the founder's son, who appeared with the group from 2018 until his retirement in 2023.

The current Sons of the Pioneers are "trail boss" Tommy Nallie (vocals, lead guitar), who joined the group in 1983; Ken Lattimore (vocals, fiddle), John Fullerton (vocals, rhythm guitar), Paul Elliott (fiddle, vocals), and Chuck Ervin (bass, vocals).

In addition to their appearances and filmed performances, their music was used in numerous other films and television shows.^[11] and for John Ford movies Wagon Master in 1949 and Rio Grande in 1950, and performed the theme song for the John Ford classic The Searchers in 1956.

In 1977, the Smithsonian Institution, which designates certain artists and performers who have made a noteworthy contribution to the arts and culture of America, named the Sons of the Pioneers as "National Treasures".^[12]

In 1995, the Sons of the Pioneers were inducted into the Western Performers Hall of Fame at the National Cowboy & Western Heritage Museum in Oklahoma City, Oklahoma.

In 2001, a book about the group was published, titled The Sons of the Pioneers by Bill O'Neal and Fred Goodwin.^[13] Another book about the group, first published in 1974, is called Hear My Song, The Story of the Celebrated Sons of the Pioneers by Ken Griffis, and is available on The Pioneers' website.

Later notable appearances include:

• An appearance along with Roy Rogers in January 1983 in season 2, episode 11 of the TV show "The Fall Guy", titled "Happy Trails".
• An appearance on Austin City Limits in season 9, episode 12, titled "Country Legends with Faron Young, Kitty Wells, Sons of the Pioneers, Joe & Rose Maphis, Pee Wee King & Red Stewart, Johnny Wright, & The Collins Sisters". The episode was taped in Austin, TX on March 07, 1984.^[14]
• "Tumbling Tumbleweeds" was used in the Coen Brothers film The Big Lebowski in 1998.

The Sons of the Pioneers were the first Country and Western group to sing at Carnegie Hall, and the first to perform at the lavish nightclubs in Las Vegas.^[15] The group has a star on the Hollywood Walk of Fame at 6845 Hollywood Blvd. for recording.

Pioneertown, California was named for the Sons of the Pioneers who were original investors. It was built in 1946 as an old west movie set.^[16]
