Hi, I was wondering where can I buy the scorebook of "Howl's Moving castle?" Because I can't find anywhere when I search. It would be great if someone tell me, because that would help me a lot. MY friend and I are planning to play the "Theme" of Howl's moving castle but we dont know where to get it at. Please help me! =)

Ok, Does anyone know where I can find "The Promise of the World" from Howl's Moving castle music sheets for violin and piano??? Does anyone? Also, where can I buy the book??
