Ray Midgley could be very intimidating though I suspect he had a dry sense of humour.
On one visit he had banged on about modern pop music. So at a coffee break Iduring field service, asked him, "well Ray what sort of music do you like then?" He said "oh something like Gilbert and Sullivan". I feigned shock and indignation, "not subversive Victorian satire; didn't you know it was considered very shocking in its day?". He just gave a wry smile.
