Phantom needs no introduction. It is one of the most popular shows ever. It is the longest running Broadway show ever, still on Broadway, infact, with 9051 performances and counting. Phantom has been playing at the Majestic since January 26, 1988. But it has been playing on West End (London's version of Broadway) since October 9, 1986. It won 7 Tony Awards including Best Musical. The Original London cast album is the eighth best selling album worldwide at 40 million copies sold.
Phantom tells the story of the strange occurances at the Opéra Populaire that involve a young girl named Christine Daaé (who has been played by Sarah Brightman in EVERY incarnation of this show >_>). She remeets an old childhood sweetheart named Raoul who is the new patron (pays to help support) of the opera house. Within a year, they are engaged. Meanwhile, the opera house is haunted by its very own Phantom, who demands payment from the new owners of the opera house, Monsieur Richard Firmin and Monsieur Gilles André, who are quite annoyed at the threats. When Carlotta Giudicelli, the opera house's leading lady throws a tantrem and leaves because a set piece fell on her, the new owners, desperete for a leading lady put Christine in the lead. When she performs beautifully, The Phantom falls in love with her. He abducts her to his lair, but releases her to continue being in the lead. Now, the owners are confounded, Raoul is upset, and Carlotta is in full diva mode from being replaced. All of these events converge to a truely epic climax.
One thing that is interesting is the famous song form the show "Phantom of the Opera" is ment to be something completely foreign. It's a rock song invading an opera house and otherwise completely operatic score.
