Barack Obama and HBO are throwing one heck of a party for the president-elect's inaugural kickoff, and they're bringing in a bevy of A-listers for the event.

We Are One: The Obama Inauguration Celebration will feature appearances by a number of musicians, including Bono, Beyonce, Bruce Springsteen, Stevie Wonder, Sheryl Crow, Garth Brooks, Josh Groban, Usher, James Taylor, Mary J. Blige, and John Legend, according to Variety.

Industry heavy hitters George Stevens Jr., Don Mischer and Michael Stevens are producing the show, and were surprised how eager the talent was to participate. Stevens, executive producer of the Kennedy Center Honors, said they only began making calls eight days ago, but got a boost when U2 and Springsteen and Brooks signed on.

"When you get three yesses of people of that stature, you know you are on a roll," Stevens said.

Jamie Foxx, Martin Luther King III, Queen Latifah and Denzel Washington will also be on hand to read historical passages. The event, being held at the Lincoln Memorial Sunday, will also reflect on great accomplishments by past presidents as well as the themes of Obama's campaign.

"[It's] not meant to be a glitzy performance," Stevens said, suggesting that even the music — U2's "Pride (In the Name of Love)", for example —will have a connection to the themes. "It will not be people singing their greatest hits. It's going to be very entertaining, but it is about a country full of purpose."

Even more talent is expected to be added in the coming days. The event will air exclusively on HBO for free Sunday night.
