I was there! Between 25th October and 10th November 1969 I wrote these notes in my diary ('Boot', aka Derek Wellington, was the love of my life at that time!)
"Oct 25 1969 - Went to London to meet Boot’s friends ‘Geoff and Pat, Hugh and Jackie and Marcus, and Terry, who were trying to get Radio Geronimo together.
Nov 9th ‘Went to Radio Lux studios [with Boot] to see them recording Radio Rupert Jumbo Blues show. [John] Peel didn’t show up but Pete Drummond came and took photo of me"

Potent times; as Barry Everett said in the film Radio Geronimo - Monte Carlo and Bust “There was something in the air, you know? There was magic, there was magic”. It was such a great station to listen to, and wonderful to find the play lists on here.

I know it's a really long shot, half a century and more later, and not actually related to Free Radio....but (!) I'm hoping to find a photo of Boot, maybe taken at one of those recording sessions? I think he was around with the team quite a lot. We were only together for a few months after that and I lost touch. But an idle google search for Radio Geronimo just a few years back threw up all sorts of good stuff about the station and the people, including a mention of Boot in a quote from Terry Yason recalling visits to Hugh Nolan's home "We would leave at dawn if at all. Robin Sendak, Maurice's nephew, Boot the artist who died so prematurely and various wastrels and misfits who felt free to turn up at any time, all were welcome…" I guess I was one of those wastrels and misfits, but I was so shocked to learn about Boot's death. For some reason I have no photos of him so if anyone else does, it would be great to see him. Sad also to read of the more recent death of Hugh Nolan.
Thanks to all who've preserved and shared this info about Geronimo.
