FORTUNE AND MEN'S EYES, written and performed about the same time that Boys In The Band premiered. Directed by and starring Sal Mineo. Of course, there is a bitchy character named Queenie.
However, this one was the first play to have a fully nude, male-on-male rape scene onstage (Mineo raping Johnson).
Unfortunately, the clip here stops just before the famous 'shower' scene. At least we get a good look of Johnson in his tighty whities.
