Arlo Guthrie tells a famous story about being accosted after a concert in 1972 by a skinny short guy who wanted to play him a song. Arlo said "How about you buy me a beer, and as long as I sit here drinking my beer, you can do anything you want?"
The skinny short guy was Steve Goodman, the song was "City of New Orleans", which became Arlo's biggest hit.
"That turned out to be one of the better beers of my life."
