6.5m viewers for charity dance show
The first heat of Let's Dance For Sport Relief attracted an audience of 6.5 million viewers, the BBC said.
The celebrity dance show kicked off with EastEnders double act Tameka Empson and Laurie Brett winning the heat and going straight through to the final after becoming Beyonce and Lady Gaga for the night.
The soap actresses performed the dance routine from the pop stars' single Telephone, a song title which must have inspired viewers at home to cast their vote.
Comedian Terry Alderton, who danced to Proud Mary by Tina Turner and wore a short flapper-style dress, was sent through to the final by the judging panel after the girls' victory.
Alderton was chosen by the judges over radio DJs Tony Blackburn and David Hamilton - performing Salt n Pepa's Push It - after their acts came second and third in the public vote.
The show, hosted by Alex Jones and Steve Jones, had Celebrity Juice presenter Keith Lemon, television and radio host Graham Norton and actor and comedian Greg Davies on the judging panel.
Missing out on a place in the final were former Strictly Come Dancing winner and cricketer Darren Gough, who danced to music from West Side Story, and Angelos Epithemiou and Ulrika Jonsson from Shooting Stars performing a tango.
The BBC said 6.5 million people - a 28.9% share of the viewing audience - tuned in to watch the show. There will be three more heats before the final when eight celebrity acts will compete.
The judging panel will rotate weekly and will be made up of comedians, some of whom are former contestants, who will review each of the performances.
Among those still to perform are Eddie "The Eagle" Edwards, Amy Childs and Harry Derbridge, Arabella Weir, Scott Mills and Olly Murs, Omid Djalili and Rowland Rivron.
