I'm not a huge follower of Broadway. Typically there are just a bunch of shows I've thought about seeing, and very few that I actually go to. Out of my entire time living in New York, I've seen one musical (compared to the six I saw on Broadway when I was living in a completely different region of the country.)
Anyhow, New York Magazine has an entertaining guessing game called Improbable Broadway Musicals: The Quiz! in this week's issue. Take a look and see how well you do. My performance was pretty awful, but not as awful as some of the ideas that really are going to be showing up on Broadway soon.
