On one of Mike's albums he does the piece, and he does it when he performs live. I haven't recovered from his performance at the Big Muddy festival in Boonville, Mo. two and a half years ago! What a funny guy! And he has a song called "Railroad Bill" (not the old folk song) that describes the trials and tribulations of writing a folksong---great stuff. If anyone wants to book him, they will get their money's worth.
