"Note: This was sourced from a cassette copy that a fan got directly from an BBC employee after writing a letter to inquire after the status of this recording. The BBC employee mentioned that this came from his private copy and that video sources no longer existed in the archives. The audio recording was first heard by the public in 1993 when it came out on a pressed CD bootleg in inferior quality. Then later in the mid-2000's it started to circulate in better quality. There is notable tape hiss at times but I think the historical importance outweighs the sonic imperfections. Four songs performed here were unreleased at the time, though already fully realized (not counting 'There's No Reason Why You Should Remember Me').
Some of the arrangements are quite different from the studio versions and there's an extra unheard verse on 'So Long, Marianne'".

"According to this site and other sources, the video recording of this BBC show was destroyed. Dave Cousins and The Strawbs have been mentioned as the backing band ant this BBC session.The sound quality is better than on the once commercially avaliable bootleg known as At the Beeb (Yellow Cat - YC 018). There is also one extra track (One of Us Cannot Be Wrong)".
