QUICK TAKES - March 4, 2009

Pop star Michael Jackson is in London this week to make a “special announcement,” representatives said Tuesday, and industry sources said it was likely to involve a series of comeback concerts there.

Outside Organisation, the music PR company that represents Jackson in Britain, has e-mailed invitations to a news conference at the O2 arena in London, where the concerts are likely to take place -- probably later this year.

Jackson and representatives from music promoter AEG Live are expected to attend the Thursday event.

The 50-year-old last appeared at the World Music Awards in London in 2006, but the much-hyped return of one of the biggest pop acts of all time was a critical flop after he sang only a few lines of “We Are the World.” The man behind “Thriller,” the bestselling album of all time, has generally kept a low profile since his acquittal in 2005 of child sex abuse charges.
