Sir Paul McCartney still has anxiety dreams about performing with The Beatles. The rock legend can't explain his weird nocturnal thoughts but admits he still has nightmares where people are walking out of Fab Four gigs. McCartney explains, "I'm there... and we're playing and the audience starts to leave. (We say), 'OK, what do we do, what do we do? Long Tall Sally...' They're still leaving, and I wake up in a cold sweat." But in real life, McCartney admits he can never recall anyone leaving a Beatles show.
