When he was hired to be the musical director for the television series, Your Hit Parade, for its 1957–58 season,[1] he replaced most of the existing studio orchestra members with his own choices including Dick Hyman, Don Lamond, Al Caiola and Jerome Richardson. At that point, the Hit Parade orchestra became one of the first on-screen orchestras to become integrated. In 1953, he produced a number of acts, including the McGuire Sisters and Teresa Brewer, and by 1958 had a hit single, the theme tune from the movie Kathy-O. In 1956, his recording of "Man with the Golden Arm" sold over one million copies as a single and was awarded a gold disc.[2]
According to The Ultimate Book of Songs and Artists, by Joel Whitburn, Jacobs's biggest hits were "Main Title" and "Molly-O" (1956), "Petticoats of Portugal" (1956), and "Fascination" (1957).
Jacobs brought a lush instrumentalorchestral sound to a number of rock and rollsongs in the late 1950s, notably those for Buddy Holly and Cirino Colacrai and his vocal quartet, the Bowties. Eventually retiring in the late 1970s, he and Harriet Jacobs wrote Who Wrote That Song?, a reference book on popular songs and songwriters.
He died in 1988 in New York City, at the age of 70.[1]
