"they might come to espouse the tradition" - but of course there are many traditions. I'd hate to think that people from any of the many immigrant and immigrant descended communities in England would be expected to reject their own traditions and adopt ethnic-English traditions.

African, Indian or Eastern European musical traditions, for example, and people who recognise these as their particular traditions, should feel at much at home in the English folk scene as Irish music already does. (And American traditional music too, of course.)

And in no way that that mean ceasing to recognise and celebrate the ethnic-English traditions, with its own special qualities.
