Sir Bruce Forsyth and Tess Daly welcome you to a very special Strictly Come Dancing as the show hotfoots to Wembley Arena for a live spectacular as we dance through the decades! Our nine remaining couples perform live in front of 6,000 people, kicking off the show with a bang with an amazing routine from our professionals and celebrities. Then each couple takes to the stage to dance their hearts out to stay in Strictly Come Dancing. As if that's not enough, the princess of pop herself Kylie wows the crowd with 'The Loco-Motion'. Voting lines will open at the end of the show. Once judges' scores have been added to viewer votes the two lowest scoring couples will perform again in the dreaded dance off in Sunday night's Results Show.
