It is hard to believe now, but some 40 years ago, during the height of the Beatles' popularity, a rumour started that Paul McCartney had died in a car crash.
Rather than keep this secret, secret, the surviving Beatles allegedly hid clues in their music, and on their album covers, that came out and said that the new Paul was a a guy hired to pretend to be McCartney.
Of course, it was all poppycock. But I can't help but think that the boys and their managers might have had some fun with these rumours, this free publicity, and deliberately planted hints here and there to add to these rumours.
People don't talk about it much any more, but they used to talk about backwards masking, where a song played backwards might reveal words you couldn't detect otherwise.
I thought I'd include a couple of links this fine, cold evening to show some of the "Paul is dead" clues. You can judge for yourself. Also, I just found a "Paul is dead" website, which tries to sell you something, but which also contains a lot of information. And, this wikipedia article will tell you lots, and send you to plenty of other websites about this hard-to-kill rumour.
Wanna read an article about backmasking? Here you go. You're welcome.
My boss, Kevin, is a devotee of this conspiracy. I wonder if he'll learn something from a perusal of this website? Hmm.
