Not only will fans have the film of [article id="1622016"]"Michael Jackson's This Is It"[/article] to look forward to next month -- they'll also have a brand-new single, appropriately titled "This Is It," and, as previously reported, [article id="1621840"]an album.[/article]

According to a release on Jackson's official site, the song "This Is It" -- which features the Jacksons on backing vocals -- will be released on October 12, and the two-disc album will be released on the 27th in the U.S. (the 26th internationally). The film follows on October 28.

"This song only defines, once again, what the world already knows -- that Michael is one of God's greatest gifts," said John McClain, co-producer of the album.

The song will close disc one of the album, which will consist of previously released versions of classic MJ songs in the order in which they appear in the film, which is culled from rehearsals for Jackson's scheduled string of dates in London.

Disc two offers "previously unreleased versions of some of the artist's classic tracks," although it does not specify the origin of those recordings; MTV News' requests for comment had not been responded to by MJ's rep at press time. This disc also features a previously unreleased spoken-word poem from Jackson titled "Planet Earth."

The compilation will also include a 36-page photo booklet including stills from MJ's final rehearsals for the London shows, which took place in the weeks before his death.

"Michael Jackson's This Is It" -- a trailer for which [article id="1621523"]premiered at the VMAs[/article] -- arrives in theaters on October 28 and runs for a limited two-week engagement, with special screenings in some cities taking place on the 27th.
