But Lynne tells the Guardian: "I was really worried before the show; I was thinking, 'What the hell is it going to be like after all these years?' I thought the crowd would all disperse and go their own sweet way - but they all loved it."

You really have to get yourself back into it. Standing up playing guitar is the hardest thing - for the last 20 years I've been sitting down in the studio playing, so you have to learn all over again."
