Old Grey Whistle Test (1)
This is an obscure performance and in fact probably the oldest TV recording made of John.
Artists listed are Bell & Arc, John Martyn.
Henry Pond reports: "I saw John on OGWT in a session which I think must have been earlier than the 13th March 73. He was playing solo, the tracks were Bless The Weather and (I'm guessing) Glistening Glyndebourne. I still have the (mono) cassette somewhere complete with background whistle where I recorded the program via microphone in front of the TV speaker."
