This is a medley of songs from the Broadway musical version of Little Shop of Horrors (which is supposed to be about a carnivorous plant that feeds on human flesh) that my choir had to sing in eleventh grade (same performance as The Time Warp). I’d never heard of the musical before I got the sheet music; it looks abysmal and I have no interest in seeing it. This is what we used to practice; it is not us singing it.
