re: My favorite conspiracy theory is that Paul died in 1966.

There was some hour long radio show (or something similar) on tape that I had back in high school that made the rounds. It walked through all of the clues and backwards messages on the Beatle albums of that time. It was pretty cool and left you with the impression that a a minimum they were trying to play with their fans that Paul was killed. There were just too many things in all of their album art and songs to be a coincidence.

I wish I could find it.
