Very sad news. Respect to John, only 40 minutes ago I was thinking about him when I was looking on Abebooks to discover that He and Jeremy Sandford had contributed to the 1978 issues of International Times, Vol 5 No 1.
He wrote to me about Harold Bayley when I discovered some of his typescipts - simply because he illustrated T&H New View over Atlantis DJ with a copy of Archaic England.
