Not exactly a death on stage... but an episode of cardiac aryhthmia (sp?). I was performing "On Ilkley Moor Bt'hat" with my band. There was an excellent sign language interpreter working at the edge of the stage. As I sang, he illustrated the various activities and animals... digging, eating, ducks, worms, courting. He was really good. Very expressive. fascinating... too fascinating. About 2/3rds through the song I realized that I'd been so fascinated that I'd not song a word for about 5 seconds, and the interpreter had caught up with me... and was now waiting for the rest. D'oh!
