Coincidences - NOT amateur radio

Years ago, I was at university with people who since became famous. I was idly looking on Wikipedia at one of these - Mark Hedley - when who should be on BBC Radio 4 "World at One" but Sir Mark Hedley! Talk about coincidences!  I also knew Robin Field-Smith who became Her Majesty's Inspector of Constabulary and an MBE. When I first came to Cambridge I slept on his floor, little knowing how famous he would become later.
