ABBA deny reunion rumours, announce tribute gig
Half of the Swedish band will take part in London Hyde Park gig
Anderson was responding to a report in The Sun, which claimed Abba are set to regroup and take over the 50 gigs the late Michael Jackson was due to play at the London O2 Arena this summer.
"No-one's asked us and if they did we wouldn't say yes," he said during an interview on 'Friday Night With Jonathan Ross', which can be viewed for a limited time on the BBC iPlayer.
However, the co-songwriter of hits such as 'Waterloo' and 'Mamma Mia' has confirmed he is to take part in a tribute gig featuring some of the Swedish pop band's biggest hits, according to BBC News.
'Thank You For The Music... A Celebration Of The Music Of Abba' will take place in Hyde Park, central London on September 13.
Bjorn Ulvaeus will also appear at the BBC Radio 2 event, with ticket details and guest vocalists to be announced at a later date.
"This must be the greatest honour that can be bestowed on any songwriter," the duo said.
