Not a folkie maybe but who cares - what a man! I've just read his obit in the Grauniad. As you say, a true eccentric of the very, very best kind. Just having a 2CV qualifies you without the rest of his incredible life. I love 'Waterlog. A frog's eye view'. Inspirational. You were indeed fortunate to have such a friend who, it appears died far too young.
