The Steve Chapin Band includes Chapin and former Harry Chapin band members "Big John" Wallace and Howard Fields. Steve and Big John have been making music together since their boy-choir days in 1955, through the doo-wop days, folk and early rock eras, and the Harry Chapin years. It was during the mid-'70s that they teamed up with Howard to forge the musical bonds that forge the heart of their music. He is also the fifth cousin of country singer Mary Chapin Carpenter.
