David, your story reminds me of a tale I read years ago. It was told by a rather famous opera singer, who's name I can't recall. When she was a young singer, and not performing in operas yet, she did perform on stage in a recital. She had a very limited repertoire and as the audience keep wanting more and more encores, she ran out out of material. Just before her final encore, she whispered something to her accompanist. Her final number brought the house down and the critics raved about it. They demamnded that she tell them what the piece was, as they had never heard it before. Years passed before she admitted that she had sung the Polish alphabet to a vocalizing excersise melody! CHEERS, Bob
