A track by U2's Bono is the latest addition to the quirky, star-packed soundtrack of the upcoming movie "Moulin Rouge," which also includes a hit cover of "Lady Marmalade" by Christina Aguilera, Lil' Kim, Mya and Pink.

Bono teamed up with a rather less famous Irish rocker, Gavin Friday, and Friday's musical partner, pianist Maurice Seezer, to record a new cover of T-Rex's glam-rock chestnut "Children of the Revolution." The album also includes a new Fatboy Slim track, "Because We Can," a collaboration between Beck and Timbaland on a cover of David Bowie's "Diamond Dogs," and two versions of the '40s standard "Nature Boy" — one recorded by Bowie and another by Bowie and Massive Attack (see "Bowie, Massive Attack Updating Nat 'King' Cole's 'Nature Boy'").

Nicole Kidman and Ewan McGregor, the stars of "Moulin Rouge," sing on several tracks, including a cover of Elton John's "Your Song" that finds McGregor going up against Placido Domingo and two other opera stars. McGregor will also sing on a tango version of the Police's "Roxanne." The album's first single, "Lady Marmalade" — a cover of the '70s hit by Patti LaBelle's former group LaBelle — has already hit heavy rotation on pop stations.

The film, set in a Parisian nightclub in 1899, is expected to hit theaters in a limited run beginning in May, and will open nationwide on June 1. The soundtrack is due in stores May 8.
