I will be attending as well. Was fortunate enough to see their second-to-last performance on Broadway last year and cannot wait to go again, and to take a friend or two who missed the New York run.
There's definitely no nudity and little if any profanity. The disturbing aspects of this show come from the way the show is conceived and staged, and from the shamefulness of the (true) story. I'd say it's just about perfect for a mature musical theatre lover of any age.
