It's surprising that David Merrick tried to pull it from the show. According to LuPone (and others) Merrick came one night and stole all the sheet music for the song.
As Patti LuPone tells it: the song was in, the song was out, the song was in, the song was out, the song was in, the song was out, the song was in, the song was out.
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.
