The Sugababes vs Girls Aloud have tonight marched straight to the top of the UK charts with their Comic Relief single Walk This Way.
The girlbands performed the remake, originally recorded by Run DMC and Aerosmith, to open the seven-hour fundraising show for Red Nose Day on Friday night.
Another act from the comedy extravaganza, Phoenix Night's Brian Potter and Little Britain's Andy Pipkin, entered the singles chart at number three with their version of 80s anthem (I'm Gonna Be) 500 Miles by The Proclaimers.
The newcomers forced Take That down to number four with Shine after two weeks in the top spot.
There was also upheaval in the UK album chart as X Factor loser Ray Quinn won the top slot. The 18-year-old Liverpudlian was pushed into second place in last year's competition final, but entered the album charts at number one with his debut offering Doing It My Way.
Take That's album Beautiful World climbed one spot to number two, while Simply Red's new offering, Stay, entered the chart at number four.
Russell Watson dropped to number five with That's Life, and the Kaiser Chiefs fell from number one to number six with Yours Truly Angry Mob.
Donny Osmond stayed at seven with Love Songs of the 70s, Dolly Parton's Best Of album was at eight, followed by Everytime We Touch - The Album by Cascada at nine and Back to Black by Amy Winehouse at 10.
In the singles chart, Gwen Stefani featuring Akon held on to number two with The Sweet Escape and Fray was another non-mover with How to Save a Life at five. Kaiser Chiefs and Ruby was down three to number six and Mika fell one place to seven with Grace Kelly.
Justin Timberlake and What Goes Around Comes Around fell from four to eight, just ahead of Camille Jones and Fedde Le Grande at nine with The Creeps and Calvin Harris, who climbed from 17 to 10 with Acceptable in the 80s.
