It's also a theater production as much as a comedy act. A 100% improvised musical based on a suggestion from the audience. One hour long. All the lyrics, melodies, harmonies, choreography are made up right on the spot. Live band makes up all the music. The comedy is hysterical, only to be surpassed by the level of talent. I've lived in Chicago for 30 years and it's easily my favorite entertainment option. Language and content can go anywhere since it's all improvised.
