Pop group Sugababes donned replicas of Abba's flamboyant stage costumes to perform a rendition of Dancing Queen in London's West End on Thursday night (15Sep11).
The Push the Button hitmakers appeared at the close of the Mamma Mia! musical to sing the legendary Swedish band's classic track as part of a charity fundraiser.
And they ensured their performance was an authentic trip down memory lane by sporting the band's famous bell-bottomed jumpsuits, flared sleeves, and knee-high platform boots.
The Sugababes' show ended a week of West End cameos by stars including Melanie Chisholm and Peter Andre, organised in aid of the Bbc's Children in Need Pop Goes The Musical fundraiser.
