Glastonbury festival - the first one!

I was there!! Me and about 900 others.

I was 19 - just into my second year of A levels at Weston-super-Mare Tech. OK A level retakes. One weekend, fed up with the usual Young Farmers drink-all-you-can weekends, or avoiding the Bournville gang, there was a pop festival at a village called Pilton not far away. In fact it was the Pilton Festival as far as I remember, not the Glastonbury Festival.
We'd all been to the amazing Bath Blues Festival in the summer - but this... What can I say! My memory of it is ...
We drove down paid on the gate (only a pound and you got free milk! Believe that??!!) and parked at the back of a field. We wandered across this not very huge field to watch the bands. I could have sworn the Kinks were there, but Marc Bolan definitely was. Obviously we had a great time but it was a small small event in a little field.
I never went again. The next year I was at Brighton College of Education and starting to book bands myself for college gigs. Fairport Convention, Steeleye Span, Al Stewart and many others.
I don't know how it progressed over the years. Have you ever heard of it?
