Going back to the early years of primary school...the whole school has assemblies in the main hall. Everyone sat down, we sang hymns - there was an old piano, and the headmaster coupld play it amazingly well. He sat down, found his page, and played...yet he never looked at the music or his hands.

But anyway, if anyone was naughty he made them get up, walk to the front, and he sat them on top of the Piano. We were all little shrimps, so it was rather scary.

One lad was yawning a lot, so he made him get up and run 50 laps round the school field.
