Rereading this thread I realized I missed a few. My all time favorite is Camelot, can't believe I forgot it. I still cry when I hear Guinevere.
Gypsy, just great all around. I saw it live years ago at PCPA Theatrefest at their open air theater. That was also where I was first exposed to Camelot. I had the chance to see
Byron Jennings perform as King Arthur.
South Park-- if it had come out on vinyl I would have worn out the grooves years ago. I loved the film too. It was a classic play on the whole parents care more about the "cause du jour" and not their actual kids, an issue that sadly we see in society.
