The Bottom Line:
Unknown number of tracks from the Cambridge Folk Festival.
John performed the 21st Cambridge Folk Festival on 27 July 1985. The material was broadcast a few months later, 22 February 1986.
The A-side contains material by Loudon Wainwright III from the same line-up.
The B-side lasts half an hour, so half of John's set was left out.
There were more transcriptions of the festival, at least twelve records must have been made.
