If everything had gone according to plan, Michael Jackson would have kicked off his This Is It concerts, a spectacular, career-reviving series of greatest-hits shows at the O2 Arena in London on Monday (July 13). Instead, Jackson's family and concert promoter AEG Live are trading barbs in the press over whether the 50-year-old King of Pop was even healthy enough to perform any of the scheduled shows, to say nothing of the 50 that were scheduled. "The comeback tour was a good idea, but the wrong idea about it," family patriarch Joseph Jackson said in an interview with ABC News.
