PJ & Duncan's classic track 'Let's Get Ready To Rhumble' is currently sitting at No.1 on the UK iTunes chart.

The duo, who are the alter ego of British TV's Ant & Dec, released the song in 1994 and it hit No.9 in the charts at the time.

They performed the song on their Saturday Night Takeaway show at the weekend (March 23) after tracks from ITV's Big Reunion acts such as 5ive and Atomic Kitten.

It subsequently launched up the iTunes UK chart and has been boosted by radio promotion.

Tweeting today (March 25) as the song hit No.1 on the chart, Declan Donnelly said:

"This is seriously nuts! I can't quite believe #LetsGetReadyToRhumble is a bigger hit 19yrs on, you're all mad! D x."
