One night I was singing an old standard of mine, and it disappeared. I kept up the guitar part as long as I dared, and then I spoke to the audience something like this: "I hope you'll forgive a little memory lapse here. It's a NEW song for me. I only learned it about fifty years ago!" Got a good laugh.Then I said, "Well, here's another song that's got most of the same notes in it!" and took off on a galloping rendition of The Great American Bum, which is a great crowd pleaser.
