Week 5: Celebrating BBC 100

Strictly Come Dancing celebrates 100 years of the BBC. The show opens with an epic group number that sees the Strictly professionals and judges gatecrash some of the biggest BBC flagship shows. Also tonight, for the first time ever, our couples perform to either an iconic BBC theme tune or dance in tribute to one of the BBC's most loved services. It promises to be an unforgettable night of celebration and dance.
