Throckmorton was born in Carlsbad, New Mexico,[1] and his family moved to Wichita Falls, Texas shortly after his birth.[2] After graduating from college, he moved to San Francisco, California and first played rock & roll before switching his focus to country music at record producer Pete Drake's suggestion.[citation needed] By 1964, he played bass guitar for Carl Butler and Pearl, and was signed to a publishing contract; his first hit as a songwriter was "How Long Has It Been," which was a Top Ten country hit for Bobby Lewis.[2] Throckmorton was later signed to a contract with Sony/Tree Publishing, but was fired after none of his songs became hits.[2]
Throckmorton returned to Texas in 1975. However, other songwriters had continued selling his songs, and he was soon re-hired by Tree Publishing. Over 150 of his songs were recorded in only nine months, including Johnny Duncan's first Number One hit, "Thinking of a Rendezvous."[2] Other artists who had hits with his songs included John Conlee, Dave & Sugar, Merle Haggard, The Oak Ridge Boys, and Jerry Lee Lewis.[2] Throckmorton was also signed to a recording contract with Mercury Records in 1976, although none of the singles from his debut album The Last Cheater's Waltz reached Top 40.[2] He was also named Songwriter of the Year by the Nashville Songwriters Association International in 1978, 1979 and 1980,[1] as well as Songwriter of the Year by Broadcast Music Incorporated in 1980. Between 1976 and 1980, at least one of his songs appeared on the country charts almost every week,[2] and overall, more than a thousand of his songs were recorded by country artists.[2] Throckmorton's streak of songwriting continued into the 1980s and 1990s, with Mel McDaniel, George Strait and Doug Stone recording his material as well.[2]
Throckmorton was inducted into the Nashville Songwriters Hall of Fame in 1985. Three years later, he signed to a second recording contract with Warner Bros. Records, releasing the album Southern Train but no singles.[2] Throckmorton retired to his ranch in Texas in 1988 to care for his dying father.[1]
In 2019, Willie Nelson recorded a version of Ride Me Back Home by Sonny Throckmorton and released an album with the same title.[citation needed]
