No, I didn't see it, but Stephen Colbert talked about it on his show last night. He said that John Lennon's message was 'Peace, the answer is Peace' or something like that.
Stephen wasn't so sure what John meant, so he immediately took out his own after-life communication device and 'spoke' to the spirit of John Lennon. Seems that John really meant 'piece' as in 'getting a piece of the action.' Turns out the afterlife is kind of expensive.
