Completing the roll-out of performance announcements for the upcoming 87th Academy Awards, it has been revealed that The Lonely Island (Akiva Schaffer, Andy Samberg, and Jorma Taccone) will join Canadian indie rock group Tegan and Sara to perform the Oscar-nominated song "Everything is Awesome" from "The LEGO Movie" on the show.

Songwriter Shawn Patterson was the only credited nominee on the track, by the way, so Samberg didn't get a chance to join the exclusive "Saturday Night Live" cast members-turned-Oscar nominees. (Check out the gallery before for that who's who.) But he'll bring some of that flavor to the show right in the thick of "SNL's" 40th anniversary celebration.

Other performances confirmed for the show are Adam Levine ("Lost Stars" from "Begin Again"), John Legend and Common ("Glory" from "Selma"), Rita Ora ("Grateful" from "Beyond the Lights") and Tim McGraw ("I'm Not Gonna Miss You" from "Glen Campbell…I'll Be Me").

Also announced today were a string of presenters for the show, including Marion Cotillard, Benedict Cumberbatch, Meryl Streep, Oprah Winfrey and Reese Witherspoon.

Oh, and yesterday the Academy revealed that Jack Black would be on hand for...something. No details. I thought maybe he'd be on hand to perform "Everything is Awesome" a la Robin Williams/"Blame Canada," but no dice. Maybe he's part of the musical number being put together for host Neil Patrick Harris by the "Let It Go" songwriters?

The 87th annual Academy Awards will be held on Sunday, Feb. 22.
