I always knew there was something off about the title song, I just didn't know exactly which bits were prerecorded and which ones sung live. The cadenza was always obviously canned since every single Christine I've ever seen does a poor job lip-synching it. It's almost as if they want you to know it isn't live, LOL.
I don't recall ever feeling disappointed that song is mostly prerecorded, and I'm usually staunchly against such practices. I guess it's a fair trade off with the neat staging. Anyone who actually thinks that all of those couples are the same Christine and Phantom that started the song off must truly believe in magic because there's no way they could suddenly appear here and there in an instant. It was always obvious there were doubles involved. I find those who act as if the prerecorded thing is a major scandal amusing, haha. With all that moving around through all that intricate machinery, it makes sense.
I thought I read somewhere that only part of the orchestra is prerecorded and most of it plays live during the title song. Would anyone know exactly which sections of the orchestra play live? At the end of the title song, there's a really awesomely manic string section that I've always hoped was live. I was extremely tempted when I saw the 3rd NT in Costa Mesa back in '08, to peak into the orchestra pit during that song but that would've been hella ghetto, so I didn't, even if the woman in front of me did. I almost asked her at intermission what she saw, but she had down syndrome and--while I've encountered many with the condition who are perfectly capable in many areas--she seemed to have a very advanced case, so I didn't bother her or her family.
Prolly should have asked. Maybe she would have said "Nothing. Absolutely nada! Just a big tape recorderrrr!" :S
