The "Hard Day's Pete" episode (16 January 1994) attracted real musicians Syd Straw (as math teacher Miss Fingerwood) and Marshall Crenshaw (as meter reader Mel Ratner), specifically. They combine forces with little Pete (Danny Tamberelli) and Clem Linnell (on drums) to briefly form The Blowholes to recreate a song little Pete heard by another, unnamed garage band. The unnamed band was played by Polaris, a.k.a. Miracle Legion, who wrote and performed the show's theme, "Hey Sandy."
A Polaris three song promotional cassingle was once offered via cereal box. "Blowhole" was a favorite insult used by little Pete.
