There's an on-going project to rescue home recordings of the London Folk Song Cellar from the 1970s'ish. Also Folkweave (all dumped by BBC R. Manchester a few years ago), Country Meets Folk, Folk on 2, etc. We have also rescued 14 BBC transcription discs of Folkweave from Australia. These are at: http://www.mediafire.com/?yotynmr4bdht5
