Vassar Clements never played anything the same way twice. He never knew what he was going to play, it just came out.
Bill Monroe didn't like that improv they Vassar did. One time they're all standing behind the stage at "The Opry." Vassar's back there talking and he left the room. Bill told everybody else in the room, "you know that man right there has ruined more fiddlers here in Nashville than I can count." Kenny Baker said, "ah, he didn't ruin me."
