Could it be any more perfect, sigh? Beyonce sang "At Last" at one of the inaugural balls, and for all the world I really felt like a guest at a grand and beautiful wedding. Maybe because that was the song I walked down the aisle to! And it helped that Michelle was wearing that gorgeous winter white gown. SIGH. It brought back such wonderful memories of Derek's and my wedding, and of course it was the perfect song to usher in a new political era. And the look on Beyonce's gorgeous face at the end was so emotional.
