There are a ton of musical theatre resources around the web that give you character descriptions, a synopsis, lyrics, etc.
Try searching the web, use google, and such and do your own research. Plus, if you do that, then when other shows come up in the future you will know where to look for information!
Not trying to be mean....just trying to help you. What's the saying? "Give a man a fish and you feed him for a day. Teach a man how to fish and you feed him for life."
