In 1971, Chris Heap moved from the riot-torn streets of Derry to the tranquillity of Oxford. Here he talks about growing up in a city dominated by the car industry and dwells at length on the glory days of East Oxford, from Irish social clubs to Silvester's hardware store. He also reflects on his time working for Oxford Instruments, a company with a pioneering role in the development of magnetic resonance imaging. He now trains volunteers for the Oxfam Superstore, which has just celebrated its 1st birthday
