As I do at work when I'm trying to avoid work, I was playing a round of Really Tough Music Trivia Categories via email with a friend of mine today.
The only rule is that the person who starts the category must also throw out the first example. Then the first person to miss loses. We try to make the categories as tough as possible.
My category today was "Bands that have exactly three members - and all three members are somehow related. First answer: Hanson...Go." We were able to come up with The Jonas Brothers and The Bee Gees before giving up. Can you think of any other answers?
