Who Shot Mr. Burns?
Tito Puente and his Latin jazz ensemble were in the episode. They sing the song "Señor Burns". Oakley and Weinstein did not know Puente well enough. They let him in the episode because Groening is a fan of Puente. They thought he would sing the song, but they later learned that Puente is a drummer and is not a singer. One person from his ensemble sung the song instead.
