After 40+ years, this still might be the strangest cover version I’ve ever heard of anything. The re-worked lyrics, where I can understand them, are hilarious. I know only two things about the Residents: they were from San Francisco, and they had a guitarist called Snakefinger. Perhaps former Bay area Bastards can add something. According to the comments, the animation is by Ivan Maximov, a Russian. I don’t know anything about him either. As far as I know, the song and animation are unrelated, but they make a perfect match. Beyond that, words fail me on this one.
