HelloGoodbye,
I gotta be honest, I'm not getting it. Even listening to it after reading what Paul's supposed to be saying, I still don't hear it. Still sounds like "Shaking (or something) in the band, in the band." Maybe it's me. I'm usually fine at hearing all the other aural clues, but this one's beyond me.
But I think I may have found a clue that I haven't seen folks mention before. In the promo music video for Strawberry Fields Forever, the one where the Beatles are playing around near a broken piano and a tree, check out about 1:20 into it. This is when John is singing, "No one, I think, is in my tree." But just at that moment, someone *is* in the tree...Paul! Just a coincidence? I think not! Is this John's way of saying that the person in the tree isn't real? In other words, Paul is dead!
I would have embedded the video in my post, but I don't seem to be smart enough to do that. (I'm not particularly bright.)
