First couple slow-dances to Al Green at inaugural ball

While President Obama didn't address the crowd (or sing) at the inaugural ball, he did speak to military personnel at the Commander-in-Chief's Ball at the Washington Convention Center. "This party is just another way to say something we can never say enough of: 'Thank you,' " he said.

Michelle Obama dazzled in a red, custom-made Jason Wu chiffon and velvet gown. The couple smiled as thousands of supporters cheered and snapped photos.

They only stayed for one dance, waved to the crowd and moved on to the next event.
