Why? They sang, as all fearful people do, to find and rekindle their courage. I am put in mind here of how central and vital singing was to those involved in the American civil rights movement. Singing is what drove the movement. People would gather in churches and sing freedom songs before going out to face angry mobs ready to curse at them, spit on them, even violently beat them. And then, after they had been arrested, they would sing on the way to jail. And then they sang in jail. These civil rights activists never stopped singing.
