During the run of the show, we performed a half-hour unscripted preshow, living life as usual in the asylum. Playgoers always entered quietly, thinking they were late. And strangely, the cast segregated itself into patients and hospital staff backstage; we were never sure if it was more than just the entrances being on different sides of the set. In retrospect, I'm not entirely sure this production wasn't all a devious psychological experiment. But hey, actors are all crazy anyway... we were better prepared than the audience.
P.S. Keep your eye on Nurse Ratched down there. That's Sharon, and we'll see her again a few shows from now in Lend Me A Tenor...
