Actually, My summer camp has done a lot of these shows.
We did A Little Night Music, and though altogether it wasn't incredible, our Desiree and Madame Armfeldt were impeccable. Desiree(I think I am spelling wrong) was probably as good as in any college production, if not professional. Armfeldt was also incredible, and did an interpretation which I have good feeling has not been seen in the theatre before.
We also did Sweeny Todd, and that was altogether absolutely wonderful. We had an actor capable of acting and singing every role. But at my camp we have a higher concentration of talented children than at school. At my school we did Ragtime, with a local high school, and it turned out pretty good. Not a high school show.
