On a night of psychedelia there can be only one definitive song and it expresses a sentiment that if we all followed, well maybe the world would be a better place, though the downside is we'd all be wearing kaftans and that is so not a good look. John, Paul and the boys, Donovan and a young Mick Jagger. See if you can spot a very young Larry in the crowd. I'm the one eating a chiko roll and trying to crack onto Maryanne Faithfull.
