Relive U2 and ABBA's sensational live rendition of 'Dancing Queen'

It's a collaboration you probably never imagined would happen, but when U2 joined forces with ABBA's Björn Ulvaeus and Benny Andersson we were treated to one sensational moment in pop history.

Performing at Stockholm's Globen Arena in 1992, Bono surprised the audience when he welcomed the Swedish pair to the stage for a special stripped-back rendition of 'Dancing Queen'.

As the performance came to an end, Bono turned to the pair and bowed to them saying: "We are not worthy!"

But the most incredible moment happened as Benny and Björn made their way off stage; with the audience continuing to sing the 1976 hit song long after the Swedish superstars had left.
