Festivals never interested me,and still don't tbh. Donington&germany monsters of rock a few times was my lot.
I think people, on the whole are treated with more respect these days. I find that we were treated like cattle in veal crates for outdoor gigs in general.
Anyway, regarding glastonbury. I was a huge Hawkwind fan & purchased the ultra rare(and much talked about)Glastonbury fayre lp.
It was a triple lp, complete with spaceship,and various hippy stuff. I was never a hippy tho'.
It was realeased in '71? The very first Glastonbury.
Bowie was good on it, as were the pink fairies and edgar broughton band.
Mh tastes changed over the years,and i sold it
