I'm watching the show on PBS which documents the making of Tony Bennett's Duet CD (which I downloaded on iTunes). Tony Bennett is the best example of why some people never quit working (and shouldn't). He loves what he is doing and he is a master. It's amazing to watch him with the "younger" singers like Paul McCartney, Billy Joel, Stevie Wonder, Bono, Sting, KD Lang, Celine Dion, James Taylor, Barbara Streisand, etc. It comes so easy to him. Not bad for 80 years old.
