That's what is written on Wikipedia, but I don't trust it; the piece that starts at minute 1:46" seems like a symphony, or an overture, do you know exactly whose it is and what it is about?
The scene of the two priests being dragged along with the two pianos and the donkey on one of them is spectacular, it gives a real idea of sexual "repression" and the message according to which sexuality was seen as a taboo; at least this is what I perceived when I saw it for the first time, it seems that the protagonist must shake off an absurd weight in order
to not feel guilty in that sense.
