Will Fly - you said:

"In my Beeb days (1968-1975) I regularly grabbed discs from the Sound Archives collection after work, checked them out and took them home to record on my cassette player - whole Goon shows, for example (now all available on the market)."

Did you ever make recordings of the Folk Song Cellar transcription discs? These would have dated to about 1966? We are missing quite a few episodes. Many thanks.
