"There seemed to be people as far as the eye could see. The crowd stretched in a great semicircle from the Lincoln Memorial around the reflecting pool on to the shaft of the Washington Monument. I had a feeling that a great wave of good will poured out from these people, almost engulfing me. And when I stood up to sing our National Anthem I felt for a moment as though I were choking. For a desperate second I thought that the words, as well as I know them, would not come. I sang, I don't know how."

- Marian Anderson, from My Lord, What a Morning (1956), recalling her performance at the Lincoln Memorial 75 years ago today after the Daughters of the American Revolution decreed that Anderson, because of her race, could not perform in Constitution Hall.
