Jackson's New Single Comes Online

  Sony Music says "This Is It" will have its premiere late Sunday, at midnight, on http://www.MichaelJackson.com.

  The song plays during the closing sequence of "Michael Jackson's This Is It" and will be included on a companion two-disc CD set. The unreleased single features backup vocals by Michael's brothers, The Jacksons.

  The documentary opens Oct. 28 for a two-week limited run and was built around rehearsal footage for Jackson's planned London concerts. He died in Los Angeles on June 25.

  The CD features original album masters of some of Jackson's biggest hits, including "Thriller" and "Billie Jean." They're in the same sequence as they appear in the film, according to the Associated Press' report.
