Hi Rossim
..and I was at Uni. I did go to a festival the following year, but that was in Somerset. I see that Country Joe and the Fish featured, though he didn't make it into the crossword. I always remember his song "What's the ugliest part of the body; some say the nose, some say the toes, but I think it's your mind."
Anyway enough nostalgia. Thanks to the Forum and Google, I now have an answer for all the clues, but there are many I can't parse and some where I don't understand the definition. But enough.
So, thanks for all the hints.
