I was already signed up to be Assistant Stage Manager for another show, but I suppose I could have backed out. So I listened to the opera again, just to confirm for myself that I don't like Wagner.
Indeed I don't. The fact that the chorus would be on stage at the beginning AND the end, so we couldn't leave, clinched it for me: thank you, but No.
It just seems to me like the music doesn't go anywhere. There's no accounting for taste, I guess.
