Correct me if this is not true but I'd heard that Steve Goodman was playing in a club with Chriss Christoferson when he did a song that "a friend " wrote when Chriss freaked out "who wrote that? It's Briliant". When Steve said "A mailman who lives in chicago" Chriss said "I gotta Meet him". It turned out to be JOHN PRINE and thats how Prine got into the scene!
(could be an urban Legend) But a good story! Raptor
