Well Macca was probably as lacklustre as an 80 year old former Beatle playing some of the hits mixed in with recent stuff, joined by two huge guests could be… which is far from the worst Pyramid headliner they could/have had. It was the last time he’ll do that, among the last of his generation to do it. Sure it was probably closer to Springsteen 2009 than Bowie 2000 but if people didn’t enjoy it it’s very easy to go elsewhere/switch channels.
People can be as cynical as they want about Hey Jude… but watching that on TV, that many people, back in that field, singing together as one, a significant chunk of the nation joining in at home, after what we have all been through? Epic. I cried, a lot.
