King was deep into his oration when Jackson, who had sung at a rally to raise money for the Montgomery bus boycott of 1956, worried that he was losing his forward momentum. She urged him: Tell them about the dream, Martin.
King had given his “dream” riff many times — it wasn’t a new element of his repertoire when he stood on the Lincoln Memorial steps. Then again, Lincoln’s speech at Gettysburg, with its biblical allusions and rhythms, wasn’t a complete original either. The result wasn’t only history. It changed history.
