I also saw this first on the big screen at Glastonbury, chewing my face off. Decided I wanted a cup of tea half way for some reason.. Thought someone had moved the bushes in front of me so I began to climb through it. The bushes hadn't moved.. I had crawled down the middle aisle in front of everyone, walked along the screen and preceded to climb through undergrowth.
Luckily some kind people came and pulled me out of the bush and explained to me what the fuck was going on and directed me to the nearby tea tent. Memory a bit patchy but I think I was having fun.
I miss the 90's sometimes.
