I was lucky enough to meet Jon briefly shortly before he died. He and his wife had a home in Barnes, London, not far from where my stepdad was living at the time. He was an absolute star, and very kind to me when I was overcome by hero-worship and lost the ability to speak coherently (very embarrassing when you're in your late twenties!).

Funnily enough, later that day I also met Aubrey Woods, who played the Controller in "Day of the Daleks". He lived across the road from my stepdad and was a classic "theatre luvvie". Very sweet man.
