I once saw on TV a well-known singer telling about the day he was performing a famous Frank Sinatra song and forgot the words to the opening line. In Las Vegas. With Frank Sinatra himself in the audience. Fittingly, I'm drawing a complete blank on the singer's name :-) ETA: Ah! Wikipedia comes through for me. It was Harry Connick, Jr. (I just pulled up male pop singers and scanned the list. I remembered the guy was a "Jr.") -- Aha! Here's a video clip [0] of him talking about it -- though I don't think this is the same one I saw. Okay, I had some of the details wrong. Anyway, there it is.
