I've just posted an obit on the BCM website -
http://www.bcmchess.co.uk. There will be more in the October BCM.
This morning I had only just finished working on John's 'Littlewood's Choice' article for the next 'ChessMoves' (I help the printer to typeset the diagrams for his column) when Malcolm Pein told me that he had died. John had sent copy to the ECF at about 8pm last night so he was enjoying his chess to the last. John sounds his usual cheerful, upbeat self in his last column. It starts "It's great to see Nigel Short back on his best form, so how about a nostalgic trip to his historic match against Kasparov..." and he then annotates the 8th game of the match where Short came close to recording a win.
I first came across John in about 1974 when I was playing for Cambridgeshire against Lancashire in the County Championship semi-final, somewhere in the Midlands. Seeing our team arrive together - we were a bunch of scruffy, long-haired students for the most part - John exclaimed for all to hear: "This lot are too young! Send them away!". But it was just his playful way of teasing us (no doubt he was reminded of his own students at the college where he taught). Didn't do him any good - we won.
