|Cover of Mahalia Jackson|
"King hesitated in the silence, and according to Clarence Jones, one of his advisers, a voice cried out. It was Mahalia Jackson, the great gospel singer. "Tell 'em about the dream, Martin!" shouted Jackson, who had been impressed by his use of the "dream" language in an earlier speech.
Suddenly, King the orator stopped reading his text and became King the Baptist preacher.
"Even though we face the difficulties of today and tomorrow, I still have a dream," he began -- much to the chagrin of his startled adviser Mr. Walker."
