Really, when you think about it, this might almost be the perfect Pancake Mountain song -- punk, with a kid-friendly-in-a-Roald-Dahl-sort-of-way narrative. The song's performed by Richard Hell (Television and a solo career, primarily), and although the song's pushing 30 years old at this point, I'm guessing this version is from his new Destiny Street Repaired release.
Really, though, it's about 10 months too late, as the animation (and song) is just about perfect for Halloween...
