Retired Gen. Colin Powell reads from Lincoln's second Inaugural address during an event to commemorate Marian Anderson's performance 70 years ago, at the Lincoln Memorial in Washington Sunday, April 12, 2009. Anderson, who was black, couldn't sing at Constitution Hall because of the color of her skin. First lady Eleanor Roosevelt resigned from the DAR in protest and along with a coalition of black and white community leaders, arranged to have Anderson sing at the Lincoln Memorial. So in 1939 she performed on the steps of the Lincoln Memorial on Easter and sang "My Country, 'Tis of Thee."
