Salve regina Dialogues of the Carmelites Poulenc 

It's hard to get hold of a guillotine these days, so we had to make do with the sound of the whip wielded by our organist, turned executioner for the occasion. We are glad you liked it all the same.

Yes, when you know the background of this play it is quite unsettling, as it is meant to be. But sure enough, apart from the 16 nuns that are successively shortened, there are both men and women in the chorus that represents the populace in attendance around the guillotine.
