FILE - In this Jan. 20, 2009, file photo, President Barack Obama and first lady Michelle Obama dance at the Commander in Chief Inaugural Ball at the National Building Museum in Washington. Obama's second inauguration is shaping up as a high-energy celebration smaller than his first milestone swearing-in, yet still designed to mark his unprecedented role in American history with plenty of eye-catching glamour. A long list of celebrity performers will give the once-every-four years right of democratic passage the air of a star-studded concert, from the bunting-draped Capitol's west front of the Capitol, where Obama takes the oath Jan. 21, to the Washington Convention Center, which is expected to be packed with 40,000 ball-goers that evening.
