Johnny Mann and his vocal group The Johnny Mann Singers were involved in several classic rock "n" roll and rockabilly recording sessions for Johnny Burnette (including "God, Country and My Baby"), The Crickets and several 1957–1958 sessions with Eddie Cochran, who was also signed to Liberty Records in Hollywood. He was also musical director of The Alvin Show, and was the voice of Theodore. Mann was also choral director for the National Broadcasting Company Comedy Hour.
The Johnny Mann Singers" instrumental "Cinnamint Shuffle (Mexican Shuffle)" hit the United States People’s chart in 1966.
Their next single, a cover version of "Up, Up and Away", became the hit version of the song in the United Kingdom Singles Chart, rather than the United States hit version by The 5th Dimension. The Mann Singers performed a strongly patriotic musical presentation at the 1972 Emmy Awards telecast hosted by Johnny Carson.
Following their performance, Carson returned to the stage and declared "War Bonds are available in the lobby," a sarcastic comment on the group"s flag-waving. The remark offended some conservative viewers around the country.
Mann wrote a number of radio jingles, the most famous being Los Angeles station 93 KHJ as well as the "Sound of the City" jingle for KSFO in San Francisco, California.
This jingle became as requested as many of the songs played by KSFO in the era of Don Sherwood, and it was adapted by Mann for other radio stations around the country which included KFRC (Department of Administration and Management) in San Francisco and CKLW in Windsor, Ontario. Mann was credited as "Johnnie Mann" in some of his earlier works. His group"s most notable alumna was Vicki Lawrence.
In 1998, a Golden Palm Star on the Palm Springs, California, Walk of Stars was dedicated to him.
