Ant and Dec top UK singles chart with Ready to Rhumble 31 March 2013 Last updated at 20:02 TV hosts Ant and Dec are celebrating their first British number one single with a re-release of their 1994 hit Let's Get Ready to Rhumble. The song made it to number one after the duo performed the track on their ITV1 show Saturday Night Takeaway last weekend, prompting fans to download it. The pair had several hits in the 1990s as PJ and Duncan, the names of their characters in TV drama Byker Grove. The original Let's Get Ready to Rhumble single got to number nine in 1994. It was their most successful release as PJ and Duncan, although they later re-named themselves Ant & Dec and made it to number three with Fifa's official 2002 World Cup song, On the Ball. The pair, whose real names are Anthony McPartlin and Declan Donnelly, announced earlier this week that they will donate profits from their number one record to ChildLine. Bit harder Speaking on the Chris Evans Breakfast Show on BBC Radio 2, McPartlin said: "I've been trying to push it under the carpet! People are still buying the track, so we've just decided that any money we make out of it will be put towards ChildLine, as we're patrons of that. On performing the routine, Donnelly said: "At 37 it's a little bit harder than 19, it felt a lot quicker than in 1994!" He added that its new success has "been bewildering." The pair also had a number five album in 1994, titled Psyche. Their other hits included Stepping Stone and Stuck On U. After rising to fame on BBC children's series Byker Grove and enjoying their stint as pop singers, they joined ITV in 1998 presenting the Saturday morning shows SM:TV Live and CD:UK. They have fronted several entertainment shows for ITV1, such as I'm a Celebrity... Get Me Out of Here! and Britain's Got Talent, and have won the National Television Award for best entertainment presenter (s) 12 years running between 2001 and 2013.
