Points
Player points are based on seating spot
Last-row seats
Chain songs from the last word sung.
No equipment, just heads full of lyrics. One player starts the chain.
Sing a line of any song, five or six words minimum. The next player must answer with a line from a different song containing the last word of yours: “…highway to hell” → “Hell is a place on earth…”. Keep it moving around the car.
Take longer than about ten seconds, repeat a song, or mangle a lyric and you're out of the chain. Last singer standing scores and starts the next chain.
Tiny words like “the”, “a” and “you” make it too easy; ban chaining on them if your car is full of ringers. Singing badly is not a foul.
