Suppose your team gets the word "red"... you now have to come up with at least 8 words of a song with the word "red" in the lyrics. If you do... the other team is in the hot seat. Can the other team do the same? It goes back and forth until one of you blows it.
The rules suffer from being a bit vague in terms of when the final category (i.e. "Boy's names O-Z") actually gets used, and the whole "pick a color" is a bit silly when the score card refers to them as "Color 1" etc instead of "Red," but I still love this game. It's best if you're with a group of extroverts who like to sing and have an encyclopedic knowledge of music and a lack of shame. Also it gets better if people don't worry too much about turning the timer over if someone is in the middle of a good song, and everyone should join in if the song is really great! This improved in England with the addition of people's knowledge of music hall tunes. FABULOUS!
