This episode is a collaboration with composer Robert Lopez, who also collaborated with Parker and Stone on The Book of Morman musical. Parker and Stone were concerned about the number of musical numbers in this episode, even though they were all short. The songs were written last-minute, as they spent most of their preproduction coming up with what the episode would be about, and then hashing out the story. Parker and Stone expressed interest in working with Lopez on a future South Park episode, but not necessarily a musical-based one.
