So, what did the creators of South Park do before they became famous? Get ready for Cannibal: The Musical, Live on Stage, a high camp musical adaptation of Trey Parker's 1995 independent film, which starred his South Park co-creator, Matt Stone. The show is a fictionalized account of Alfred Packer, the only American ever to be convicted of cannibalism. Packer is the legendary "Colorado Cannibal" of the 1870s, a cult figure among students on many college campuses in that state. Musical numbers include "When I Was on Top of You," "Hang the Bastard," and "Let's Build A Snowman."
