I've got two different books of sheet music for this show, and they both look the same, so pay careful attention before you buy one! One of them is vocal selections with piano accompaniment, and the other is vocal and piano arrangements. The difference being, in the first one, the piano rarely, if ever, has the melody in a song. Which can be good or bad depending on your purpose. If you are planning to use the music to sing, the piano accompaniments are definitely better, as they provide a richer sound to complement the vocal melody. However, if you are just planning to play them on the piano, then the second book is your better choice, as these arrangements have a piano melody in them. I'm glad to own both, but I will admit that I do use the second one more, since I'm all about the piano. :-)
