Sir Bruce Forsyth and Tess Daly present the first part of a two-night Strictly spectacular. Holly Valance, Anita Dobson, Audley Harrison, Dan Lobb, Lulu, Robbie Savage and Russell Grant take to the floor with their professional partners to perform either a waltz or a cha cha cha. There are no phone votes, and no-one will be leaving the competition, but the couples are under pressure to impress the judges, who will still be scoring.
