"Too Much Light Makes The Baby Go Blind," one of the longest running shows in Chicago history and a fixture at the Neo-Futurarium in Andersonville, is to close Dec. 31. The comedic, sketch-style production, which has played since 1988, has reached thousands of audience members and is known for featuring 30 plays in 60 minutes. But it now appears to be the victim of a dispute between Greg Allen, who created the piece, and The Neo-Futurists, his longtime collaborators, former artistic home, and, for many years, his licensee.
