I haven't been to this either. Mostly because everything is miles from everything else, you probably can't see the stage for any of the good acts and you have to stand far too close to people you normally wouldn't even share a town with.
But...I do like a huge variety of music and watch quite a few of the sets. Robert Palmer was good, liked Youngblood, impressed by Leon Bridges and thought Noel Gallagher's band was excellent (Have to listen to some of their stuff now). Can you imagine how many miles you would have to cover to see all of them in the flesh on site? You couldn't, or wouldn't want to, get around that quickly. Macca was a bit dull I thought and it was only his two guests that brightened up his set. Still, all credit to any 80 year old that can even get close to that.
I did notice though, that the BBC coverage kept picking out black and ethnic people in the crowd as if to prove Lenny Henry wrong.
I always wondered why Pink Floyd and Fleetwood Mac never did Glasto. With their giant sounds, they would be perfect for this environment. Then I might buy a ticket and sleep in a yurt for a few days.
