A startling one in 10 British adults apparently went to a music festival this year. Given that I’m a music journalist and I didn’t, maybe I’m some kind of astronomically unlikely anomaly. I’d like to think so. But those familiar aerial shots of Glastonbury – not just a few fields but a sizeable expanse of Britain’s patchwork-quilt landscape, completely overrun by an infestation of teeming humanity - is enough to make me feel smugly sane to have decided, as usual, to just remain cosily at home watching whatever the BBC had decreed were the best bits.
