Not Tony Bennett

In Monty Python's final and greatest sketch film, Monty Python's The Meaning of Life (1983), the newly arrived denizens of Heaven are serenaded by this gent with the white-guy-afro (Graham Chapman), who, despite what you might think, is clearly listed in the credits as Not Tony Bennett. He sings "Christmas in Heaven," a rich Vegas-y show-stopper production number with all the hot topless angels in Santa-type costumes you can stand.

He is one of two "not" artists in the movie, the other being Not Noel Coward.
