Stage productions of musicals? I've only seen one of them. I like stage productions of college football games.
I have not seen many plays at all, though I cowrite one in high school that we produced and was seen by the entire school. It was awful, truly awful, I had not realized how bad until I watched one from the audience. The students liked it, it was not school. It was a parody of Julius Caesar. It was awful. No music though.
I'm trying to get back to writing novels, kind of hit a soft spot of late.
