By Zack Quaintance — If you’ve ever engaged in serious Beatles fandom (and even if you haven’t but just like a good crazy theory), chances are you’re aware of the Paul is Dead theory. Essentially, this idea posits that during the 1960s, Paul McCartney died in a car accident, and he was replaced by a look-a-like so as not to disrupt the Beatles absurd fame and profitability. The label and whoever else was in on it, and the other Beatles knew but were unable to really tell anyone, so they peppered (heh) clues to the Paul is Dead theory in their songs.
