LOS ANGELES (AP) — Some of Oscar's most memorable moments have come during performances of nominated songs.

Among them: rap group Three 6 Mafia surrounded by streetwalkers as they performed "It's Hard Out Here for a Pimp" from "Hustle & Flow" in 2006, and Celine Dion's resplendent performance of the "Titanic" hit, "My Heart Will Go On," in 1998.

Don't expect such musical moments at the 82nd Academy Awards.

The artists behind the year's five nominated songs will not perform during the Oscar telecast. Instead, the songs will be showcased with clips from the films that featured them, "which is how most nominated achievements are featured within the show," Academy of Motion Picture Arts and Sciences spokeswoman Leslie Unger said on Wednesday.

That means Randy Newman won't get to take the stage for his two nominated tunes, "Almost There" and "Down in New Orleans" from "The Princess and the Frog."

Marion Cotillard won't reprise her sexy, heart-wrenching performance of "Take It All," written by Maury Yeston for "Nine." Reinhardt Wagner and Frank Thomas can't bring their "Loin de Paname" from "Paris 36" to life.

And "The Weary Kind (Theme from Crazy Heart)" won't be performed by "Crazy Heart" star Jeff Bridges or its writers Ryan Bingham and T Bone Burnett.

"We haven't been invited," Bingham said, seeming a bit surprised.

There will still be dancing on the show. Producer and choreographer Adam Shankman announced on his Twitter page that he cast 69 dancers for the show's production numbers, though he hasn't revealed exactly what he has planned.

The Oscar troupe includes at least a dozen dancers from the Fox reality show "So You Think You Can Dance," where Shankman serves as a judge. "All there for the movies!" he tweeted.

The Academy Awards will be presented March 7 at the Kodak Theatre and broadcast live on ABC.
