Tess Daly and Claudia Winkleman launch a new series of the celebrity dance contest, pairing up the 15 celebrities with their professional dance partners. 2016 champions Joanne and Ore return to perform their winning jive, and there is music from Shania Twain and Rita Ora.
The celebrities take to the floor for their first group dance, and there is a very special group routine as everyone on Strictly pays tribute to Sir Bruce Forsyth.
