Fans, museums and some members of Michael Jackson's family will mark Friday's one-year anniversary of the singer's death with special exhibits, tributes and flash mob dances from Manila to Manhattan. In the family hometown of Gary, Indiana, matriarch Katherine Jackson will unveil a monument to the singer outside the humble house where the legendary Jackson 5 began their singing career half a century ago. A memorial and candlelight vigil will follow, ending with the song "We are the World." Jackson's children - Prince Michael, Paris and Blanket - are expected to mark Friday's anniversary privately in Gary. By contrast, in the Philippines prisoners who danced their way to fame with their "Thriller" YouTube video in 2007, will pay homage to the singer with some more fancy footwork.
