There is, once again, always a song lyric. By Half Man Half Biscuit, although I can't actually ever remember which song, "They call Glastonbury "Glasto" / they'd like to go there one day / when they've put up the gun towers / to keep the hippies away"Glastonbury is going to end like wetter version of Coachella anyway
(See also the Jack Monroe thing about wearing a stab vest at Glastonbury...)
