Why doesn't ALW's original musical state that the Phantom's name was Erik?

Along with the mistery that goes with not knowing the phantom's name, I also think it creates もっと見る sympathy from the viewer. I mean, think about it--no one was even kind enough to give this poor man a name. It highlights furthur how horriby he was treated. Althought it would have been nice to know his name, especially if あなた have not read the novel and one of the many fictions following the original. As 発言しました before this also make the phantom all the もっと見る curious. Who wouldn't be facinated によって someone simply knows as "The Phantom"--I know I would be rivitted.

I've always wondered that as well. It could be because they wanted the character to be もっと見る mysterious. Not knowing the name of a character can definitely achieve that.
