Your name is either Scott, or you just came to hear about the Beatles. But anyways, yeah, back then they had a crazy high taxation rate on the wealthy, and Harrison just learned that he was part of that club all of a sudden. I don't think it's being based, I think it's part of a "Free gibs pls" thing.
Pay attention to the bass line@0:57 , it suddenly goes Blackbird. Speaking of Blackbird, it's a favorite of mine. Paul can play genius-tier bass lines.
