Concert-goers at Hard Rock Calling in Hyde Park Saturday night got a comprehensive experience of live music British style.
First there was the mud underfoot and the driving rain which arrived around half way through an epic three hour set by Bruce Springsteen. Then there was the stoicism of hardened music fans schooled on many summers of wet weather festivals.
And then there was a Beatle. Sir Paul McCartney, the UK's own most-enduring music legend joined Springsteen for sprawling, high energy renditions of Saw Her Standing There and Twist and Shout.
And then there was the petty bureaucracy. The organisers, no doubt fearing the dangling sword of Westminster Council's licensing department, pulled the plug on Springsteen and McCartney just after 10:40pm, denying them a final song and the opportunity to thank the crowd due to a 10.30pm curfew.
Instead, fans were left with the uncomfortable spectacle of Springsteen and McCartney trying to launch into a final number, unaware nobody could hear them, before the whole thing petered out with a resigned wave and a shrug from a silenced Springsteen.
It wasn't very Hard Rock, but definitely the way we roll. Rules are rules and schedules are there to be adhered to. No matter how many legends you have on stage, the good people of Mayfair and Marylebone need their beauty sleep.
Springsteen's guitarist and Sopranos star Steve van Zandt was unimpressed and took to Twitter in search of answers:
Rather than focussing on what had been an incredible concert, media coverage of the event has since focussed on its abrupt end and questions about London's fitness to host such high profile events.
