Late afternoon activities - a version of musical chairs

1. take some teachers, say five or so
2. add eight hours of dances
3. add refreshments
4. place teachers in the front row with only five seats available
5. ensure they all need to see their dancer at different times from the best angle
6. watch as they race for a better seat when the music stops
7. repeat
8. add wine - if the canteen is open :)
9. report back in under 250 words, with diagrams and references
10. point awarded for the most unlikely answer

Back in the real (reel?) world, the dancers have been called to marshalling for their soft shoe round.
