I never went once for a headliner. Was always about the little tents and stages, plus random shit going on. I think at least two I went to I never went anywhere near the Pyramid Stage all weekend
Similar for me but every time I went to see one of the headliners that people (mostly who don't go to Glastonbury) complained about, I was absolutely blown away by them.
I guess so but I don't think anybody I know has ever gone there for a headliner. Apart from maybe my wife who came along to see PJ Harvey once.
