Davis the art teacher was a lovely bloke, had a few pints with him a few year's after leaving in some pub in Harrow Weald.

He was passionate about his subject and I always wondered how he could see what you were doing when he was facing the opposite direction ... those immortal words "I CAN SEE YOU BOY!" while facing the other way and being able to point to the exact individual responsible.
