London, July 2 (ANI): Pop legends ABBA have apparently been approached to fill in for the 50-show run previously planned for Michael Jackson at London's O2 arena.

AEG Live, the promoters for the King of Pop's slated comeback tour, are said to be trying hard to woo the renowned band out of retirement.

There's a little foursome out in Sweden we keep talking to, British tabloid The Sun quoted the firm's chief David Campbell as saying.

Jackson was due to begin his This Is It gigs on July 13.

His sudden death has left the organisers facing a multi-million pound black hole if they are unable fill the slots. (ANI)
