Had the pleasure of seeing Harry Chapin in Boston back in 1973 or so.. he was the opening act for Carly Simon. He stole the show. Excellent. I have many faves, its hard to narrow down to just one. I have to say one of my all time favorites is Neil Young.. no wait - Bonnie Raitt.. although.. see, its difficult. Kinda like Lays potato chips.. just can't have one..
