Have you ever noticed how sometimes, the Beatles seem to reference parts of their lives before they even happen? In Magical Mystery Tour, George is sitting by a sign that says: "Two wives and a kid to support", and that's just what he had in the end - two wives and one kid. Ringo sings about his girl being in a car crash in Don't Pass Me By - and later, he and Barbara got engaged after they were in a car crash together! On a sadder note, if you watch the Beatles interviews after the Shea Stadium concert, John says the Beatles will go back to tour America "if we're still alive when we're forty."
Funny, isn't it? How did they know?
