Michael Jackson's death—tragic though it was—may be the impetus for a reunion tour for his siblings. The four Jackson brothers—Jackie, Tito, Jermaine and Marlon—who once comprised the uber-successful R&B group The Jackson 5, along with the late King of Pop, have been in talks with AEG Live about performing at the O2 Arena in London. The brothers are hoping to take over some of the dates the venue had scheduled for Michael's comeback concerts.
