Well, it was a baited anecdote, but I didn’t set it up well. There is no one in the band named Marshall Tucker, of course. They took their name from an envelope they found in a house Marshall Tucker used to live in. He was a blind man and my wife used to read on the radio for the Commission for the Blind. She met him at a commission banquet.
Edit: Wikipedia gives a different, and probably more accurate, account but the story is basically the same.
