Get ready to hear a lot more of "At Last" -- the song Etta James
, among others, famously covered, and which Beyonce
gave a spin more recently in her role as James in the film Cadillac Records
. Beyonce will deliver her version to the world live tomorrow, as she serenades First Couple Barack and Michelle Obama
during their "first dance"
on inauguration night (who knew there was such a thing as a first dance? Not me, obviously). To preview tomorrow's historical slow dance, you can check out Beyonce's vision of the song here
