Obamathon Includes Garth, Jennifer Nettles, The Lion King's "We Are One"

No smashing guitars this time, as
HBO will kick-off Inauguration week with an exclusive presentation of the star-studded opening ceremony on Sunday, January 18th. In the spirit of unity and inclusion, the show will be made available to all cable and satellite subscribers.

Don't expect a greatest-hits concert. The 90-minute show, which will begin at 2 p.m. and which will be shown that evening in a special free broadcast, will consist mainly of performers covering songs that have historical resonance or connect to the theme of the concert, dubbed "We Are One."

Jennifer Nettles and another yet-to-be-announced artist to sing "My Country 'Tis of Thee," which opera star Marian Anderson famously sang at the Lincoln Memorial in 1939.

Beyoncé, Mary J. Blige, Garth Brooks -- and that's just toward the top of the alphabetical list released yesterday -- are scheduled to perform.

The event launches what promises to be a heavily covered several days of activities leading up to the January 20th swearing in.
