John was born in Brooklyn, New York. Under the name of Bobby Pedrick, Jr., he first hit the popchart in 1958 when he was only 12 years old with "White Bucks and Saddle Shoes" written by Doc Pomus and Mort Shuman. As the lead singer of Bobby & The Consoles, he had the minor 1963 hit entitled "My Jelly Bean" on Diamond Records. By 1965, he had changed his name and signed with MGM records for two ill fated singles. In 1967, he signed a contract with Columbia records and released a string of singles with help from writing partner Mike Gately.
The 1980s saw John recording for Arista Records with collaborator and guitarist Bobby Mancari and keyboardist Steve Butera. A newly recorded version of "The Lion Sleeps Tonight" was released on his 1992 greatest hits album.
