You could probably add a larger ensemble to 13. It's perfect for high schools because all the characters in the show are in high school. I hate watching kids play adults.
i'd recommend "A Tale of Two Cities" in a heartbeat. My daughter was in the first ever H.S. production of it last summer in Cherry Hill New Jersey. The show was great. The kids absolutely loved doing it and depending on where you're located, the writer actually came to two of the double cast performances and met all the students. It was fantastic - the kids were over the moon!
I know they've got an album of the music coming out soon but for now you can only get it through PBS websites as they just did a tv concert special of it. The other thing is that our school actually rented the Broadway costumes to use in the show and the producers are willing to do that for other productions.
Sam French website says it's not published yet but i know for a fact they are currently licensing productions all over the place so just inquire. http://www.samuelfrench.com/store/index.php
At this point it's out of our hands. Our director is going to choose out of the two.
johnnyg - holy, that school must have an amazingly large budget! I can't say the same for us. But that sounds great for them! They must have been thrilled!
