For the first time in Strictly history, it's Icons Week in the ballroom! Tess and Claud welcome our couples back to the dance floor as they perform routines that honour some of the most influential music artists of all time. Our very own dance icons, Craig Revel Horwood, Motsi Mabuse, Shirley Ballas and Anton Du Beke, offer their opinions before the public vote opens. Who will deliver a legendary performance?
