The 50-date tour Michael Jackson was planning before his death is now going to be a tribute show for the late singer, reports say, and the search is on for replacement acts to take centre stage.

British tabloid The Sun has even said aging Swedish pop group ABBA, who previously swore they’d never play together again, will reform for a special tribute – and a huge paycheck.

They might need to work on their costumes if they do!

While several of Michael’s siblings are believed to be performing at the planned gig, critics say their presence alone will not be enough to draw a crowd.

"Fifty nights is absolutely out of the question," one source said. "Nobody in the Jackson family is capable of selling out the O2 for even one night, not even Janet.”
