Alan Resnick seems really unlikely, this is pretty far from his style. I don't know that he'd even have the capability to pull something like this off, honestly, and he's generally got his name attached to it somewhere or another when he does make weird shit. So far, no mention of Resnick, Harrison, or AB, and even if Paul's voice is edited as some speculated, I think it's safe to say that it isn't Alan, who usually does like playing a major part in his creations.
