That being written, I'm not certain about Peter Pan as a follow-up to Sound of Music. Sound of Music is so well known, where as Peter Pan (the original with Mary Martin) has a niche following I think. Perhaps I'm wrong but songs like "I'm Flying" just aren't part of the typical theater fan lexicon, let alone the non-theater person. Rumor has it that next year they are looking to do Music Man. I think by choosing a better known property, they would and will get a larger portion of the audience.
Now, what about the production itself?
