Tess Daly and Claudia Winkleman launch a new series of the celebrity dance contest. The journey begins as the red carpet is rolled out to greet the 15 stars before the nail-biting moment when they discover who their dancing partners are. Then the couples take to the dance floor to perform together for the very first time. Plus, music performances from soul legend Smokey Robinson, Imelda May and new band Five Seconds of Summer.
