"Big" John Wallace was a bassist and backup singer with Harry Chapin starting in 1971. John started his relationship with the Chapin brothers at age nine. Though the Chapins (Tom, Steve, Harry) had some minor musical gigs in their early years, it wasn't until the 1970's that they would have any commercial success.

When Harry and his brothers went on tour in 1971, Harry asked John to play bass and sing backup vocals for his band. John Wallace performed with Harry for ten years until Harry's death. In live concerts, Wallace would sing very high head tones on songs such as "Taxi".

After that John started a computer graphics company. In 1991 the band he spent ten years with was reunited and they still play to this day.
