If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
I was recently involved in a production of "Hair" where the cast was all high schoolers. It was a huge challenge but turned out very well! Definitely a musical about social issues and a very non-traditional choice to consider.
I saw The Spitfire Grill a few years ago, and even though it could have been better in areas, it's music is beautiful, and the story is pretty good as well.
