I just discovered this thread and it looks like I'm about five years out of sync but ... I have a whole raft of reel to reel tapes I recorded back in the mid-70's when I was in the US Air Force stationed at RAF Mildenhall. I know some of them were of Folk Weave and I went looking for one specific tune that I recalled recording. That tape was done on 1 Jan 1976 on Radio 2 ... my tape is a 4-track tape and I saved space by recording in mono so there's different content on the L and R stereo channels. Anyway, this particular broadcast featured material from the Deanwater Pub in Woodford and the Centre Folk Club in Portsmouth. I'm pretty sure I have other similar recordings dating from that time ... it's certainly interesting to read the comments in the thread ...
