Music to Musicals

I've been rather interested in a (always) favorite musical of mine: Sweeney Todd. I LOVE Johnny Depp and was first introduced to this musical when it was suggested to me as a movie remake starring J.D.. It is amazing and even features one of the Volturi (from New Moon), and the ever popular Helena Bonham Carter (Harry Potter[if you've seen it]) AND (YES, AND) it has the most amazing director, Tim Burton. Just wanted to throw all that out there. Boy! Can I babble, or what?
