After the swearing in, the speech and the parade, there's just one major obstacle for Barack Obama on Inauguration Day: the first dance.
The president and first lady Michelle Obama will twirl their way through 10 official balls Tuesday night with an all-star ensemble backing them up, starting with a serenade of Etta James' "At Last" by Beyonce at the Neighborhood Ball.
The event for D.C. locals will be broadcast on ABC with performances by Beyonce and her husband Jay-Z, will.i.am, Mariah Carey, Alicia Keys, Shakira, Sting, Faith Hill, Mary J. Blige, Stevie Wonder and Maroon 5.
Then it's off to Obama's Home State Ball for Illinois and Hawaii with Jack Johnson and Common performing; the Commander in Chief Ball for the armed forces with Jon Bon Jovi headlining an event to be broadcast to troops overseas; and the Youth Ball with Kanye West, Kid Rock and Fall Out Boy to be broadcast on MTV.
Obama and Vice President Joe Biden will also both also attend a ball for Biden's home states and five regional balls, with performers including The Dead, Marc Anthony and James Taylor.
In the past, inaugural dances have tended to be awkward affairs. The president and first lady take to the dance floor before thousands of supporters, twirl around awkwardly, then wave goodbye and move on to the next ball.
In 2001, reporters timed George W. Bush's forays onto the dance floor at each of nine inaugural balls. His first was 29 seconds. The longest stretch: 67 seconds.
"I confess I'm not the world's greatest dancer, but you're going to have to suffer through it," he told the crowd at the Florida state ball.
But expect a bit more from Obama and his wife, who have already danced at the concert at the Lincoln Memorial and were willing to boogie on national TV with Ellen DeGeneres.
The official balls are just the tip of the iceberg for a Washington party that has brought much of Hollywood to the shores of the Potomac. Also Tuesday night is a star-studded event put on by the Creative Coalition with Anne Hathaway, Ron Howard, Spike Lee and Susan Sarandon; a concert with Rihanna; and a BET ball with Blige, Queen Latifah, Tyler Perry and Joss Stone.
