Singer-songwriter Tom Chapin, a guy whose career spans five decades, has remarkably released 26 albums and won three Grammy Awards. He brings his laid-back tunes to Cain Park tonight at 8 for a concert that pairs him with the Chapin Sisters. Tom Chapin will accompany himself on guitar, banjo and autoharp, and his two band members will sing and play multiple instruments, including keyboard, accordion, bass, pennywhistle and concertina.
