We went over Lead Belly's repertory with him. And we helped him round it off into concert form so that when he got up in front of his audience, he sang ballads and work songs and lullabies and children's games and square-dance tunes, the whole thing.
The British ballads became a new kind of form in their hand. And out of them came the blues, a new kind of song of commentary and satire, a song form which, after all, has become the main musical form of the whole human species.
