Saw him live... the concert started without him, then he screamed from the bleachers to stop, and climbed down from a rope. I don't remember what was performed, because my memory probably confuses the concert with my favorite recordings: 1712 Overture, Bach Portrait, and the piece with the tromboon (double-reed mouthpiece hooked up to a trombone; one of the most obnoxious sounds I've ever heard).

Oh, and we can't forget "Coy hotsy-totsy." (Koyaanisqatsi)
