I'm going to start a contest. Tell me what the most irrelevant song in the history of pop music is. I'm thinking it's "everybody was kung-fu fighting." I've been told it's not secretly about anything -- it really WAS just about kung-fu fighting. There's that "Convoy" song, too. But if I say they were all in the '70s, that might be prejudiced. The "Curly Shuffle" was in the '80s.
Oh, you win nothing.
