I googled Lincoln Folk Festival and found this thread having just come back from T in the Park with my 15 year old son. Lincoln in 1971 was my first festival; I was 14 and my elder brother drove me up there from Worcestershire in our mum's Mini Traveller, so I was trying to explain to my son the differences which 40 years have made to festivals....My least blurred memories are of Tom Paxton, The Byrds, and Buffy, but the stories for my son were of the toilets - especially the torching thereof, and the lack of any commercial food outlets, which meant that by mid morning on the day of the festival, the only local shop had been stripped completely bare of anything edible!! Happy days.....
