Jerome Robbins was a choreographer and director. In the 1950's he named names to the committee, thus ending the careers of many of Zero Mostel's friends. In the 1960s', "A Funny Thing Happened on the Way to the Forum" was failing out of town. The producers decided the only person who could fix it. Zero was the star. Zero (performed by Jim here in "Zero Hour") tells the story of what happened at that first rehearsal.
