Saturday Night Live

McCartney performed "Maybe I'm Amazed" early in the night and Simon closed the show with "Still Crazy after All These Years."

Rock legends Paul McCartney, David Bowie and Bob Dylan all turned up for comedian Jimmy Fallon's opening monologue on 'Saturday Night Live' last night. And one of them even showed up in person!
