Agreed that Fair Annie is excellent, but it was a limited edition cassette. I also saw Peter, Anthea and Chris Birch in concert in Luxembourg, (in 1984, I think it was) and they performed several of the songs fom Keep on Kipling, which had just been released.
(Chris lives in Luxembourg)

I also had the chance to accompany him on harmonica at a private party, when he played blues guitar - rather unexpectedly.

I do have a copy of 'The Fox jumps over the Parsons Gate' but I think that like a lot of his stuff, it was 'Bulmerised' and unlikely to be available as a re-release in the near future (if ever)
