"So how is a kid of the X-Factor-viewing generation ever going to hear about it? "

By being different, by being curious, the same way we got into it. I was the only kid at my school into folk music, it was a happy chance encouraged by a family friend. Traditional folk was no more mainstream at the end of the sixties and early seventies than it is now. It was there if you tried to find it (it's a lot easier now) but it was down to you and us. We found it, some kids still find it, they are the "us" of tomorrow.
