There's a story Shirley Collins tells of being on that field recording trip in the Sixties, and they'd been recording at some white church, lovely music and lovely people.

And afterwards she was talking to one of the ladies who'd been singing and she started saying how great it was that there weren't any niggers in their part of the world, and how something had happened when some tried to move in which would make sure there wouldn't be any more, and she was proud of that.

When I heard that story it sent a shiver up my back. Almost makes you feel frightened to listen to some music in case it draws you in to feeling too close to something unspeakable. And yet it's beautiful music, and I'm sure beautiful people most of the time and in most ways. It's a mystery.
