Fans downloaded the song after watching the duo sing the retro song on their prime-time TV show, which featured bands from The Big Reunion.

The presenters shocked fans when they resurrected their alter-egos PJ & Duncan and the pair were seen dancing around the stage in their old get-up of shell suits and trainers.

Despite releasing the song nearly two decades ago, Ant and Dec still remembered all the dance moves.

On Sunday night Dec told fans on Twitter of his shock at the song performing so well.

He wrote: 'I know the charts have slowed down a bit but taking 19 yrs to get to No.3 is just plain ridix. D #LetsGetReadyToRhumble (sic).

In behind-the-scenes footage of the rehearsals ahead of the show the duo talk about how they feel about performing the track.

Any said: 'It was weird when they first suggested the idea and we were like oh god no really, really.'

Dec joked that the music felt fast, nearly a decade later and said: 'We have obviously aged a bit we’ve either got a lot older and slower of the track has got quicker.'

While fans might be hoping for pair to return to music Ant and Dec have set their sights on taking Saturday Night Takeaway to America.

Ant told The Sunday people: 'We want to take Takeaway to the States as we think it's a great show. We think it would be brilliant for the American audience.'

'It could be great. It's the right time to give it a crack. USA Takeaway should work so it's something we think would be really good to do and make happen.'
