We once heard Arlo Guthrie tell a story about playing a gig in Chicago. After it was over, some guy named Steve Goodman wanted to play a song for Arlo to hear. Since he gets these requests all the time, Arlo said, "I'll tell you what - you buy me a beer and you can play and sing for me until I finish it". Steve played "City of New Orleans" and the rest is history.
Don't know if this is true. One can never tell with Arlo.
