I went to one of his 25 concerts and he was clearly unwell with a very heavy cold. He still belted them out and was Amazing.
Years ago when I lived in North London I was crossing the quiet circular road between Primrose Hill and the zoo. He was crossing the other way and my jaw dropped as I starred at him star-struck. As he crossed by he turned his head to mirror mine, jaw dropped surprised and said "Oh my god......It's you!" then he laughed warmly and carried on walking into the park. Awesome sense of humour and so grounded in real life.
