This is one of those "Google the name of someone you used to know" things, but this time with the saddest result. I'm so sorry to hear that Nick has died, so many years too soon. I remember him from a Barts nurses' shared house in Stoke Newington in 1974/75. There were five nurses in the house including Nick's sister Jane and my sister Catherine. Nick and I used to go and stay, sometimes at the same time. My two memories of Nick are of the most disgraceful way to eat an orange that I've ever seen, and an Elvis impression that was ridiculously good for a fifteen year old. 

I send my heartfelt commiserations to Jonathan and Heather, who I knew, and to everyone else who knew and loved Nick.
