The Take That reunion crasher headlines two big gigs. With a full arsenal of stadium-swelling hits which we don't even need to list (oh, all right: 'Angels', 'Millennium', 'Let Me Entertain You', 'Strong'…) and bags of charisma – or, for some people, arrogance – Robbie should play a blinder. Professional cheeky chappy and former 'X Factor' runner-up Murs supports.
