The theater was originally built for performances of Princeton's Triangle Club, an acting group. This was way back when Princeton was all male. Triangle shows developed a tradition of an all male kick line in drag, a tradition that continues to this day even though the club now has about as many women as men members. My wife and I went to a Triangle show (still held in McCarter) several years ago and now my wife insists on going every year. I'm pretty sure it's the kick line - go figure!
