Back of Jay-Z Performs Before Beyonce's Big Gala Performance Jay-Z and Mary J. Blige took to the stage last night to perform at "In Concert of the Eve of Change" before this morning's inauguration. With Abraham Lincoln on his shirt, the rapper put on his second show of the weekend. Jay has played as much of a part as he can throughout the election, and tonight his wife Beyonce Knowles has the honor of singing "At Last" during Barack and Michelle's first dance as President and First Lady. After a long night of parties and shows, this morning's swearing in and speech were the emotional height of the weekend, and now it's time to celebrate our new president.
