Too Much Light Makes the Baby Go Blind is a landmark improvisational musical comedy that premiered in Chicago in 1975. Created by members of the Second City Training Center, the show consists of 45-minute productions of 30 plays based on Grimm's Fairy Tales, performed entirely without rehearsals or scripts.
