ALW wrote Norma as a belt singer (Patti LuPone). I don't know that I agree with that. I always thought Norma was more ethereal. There are about three motifs that are repeated over and over.
The set was the highpoint of the show. It moved forward and backward and up and down. It was a huge set, which dwarfed poor Elaine Paige when she was playing Norma.
You need to watch the movie "Jeffrey" where Nathan Lane plays a show tune singing priest: Sunset BOU-leevard.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
