Only met John the once at Doncaster a couple of years ago when he was good enough to sharpen a few end mills for me. They're still in the tobacco tin at the moment to remind me of what my own efforts should look like. 
I first came across him well before the inception of this forum, on the old model engineering usenet group, and gained a deal of respect from this wide knowledge then.
Wishing you all the best for a speedy recovery.
