I was thinking of this one for anther thread but with my failing memory I was going to forget someone that was memorable..... Can anyone help me complete the list of artistes appearing?

This was for, what I think was a one off Festival, of all acoustic acts, but on the lines of the big rock festivals held at the time. It was held at Lincoln UK in 1969, 70 or 71... I wonder why I can't remember it better?

I suppose this is a bit of a long shot but there were a lot of people there after all, so there must be someone out there who can help. They will surely will never forget the toilets, which was a long trench, well I won't go into that now, but I nearly did then!

Sandy Denny Band
The Incredible String Band
The Byrds
Buffy St Marie
James Taylor
Sonny Terry & Brownie McGhee
Dion

That list was in no order at all.
