Most people in many parts of the world, including England, grow up cut off from any kind of traditional musical culture. If when they come up against a musical tradition they find it stimulating and appealing, the natural thing is to explore it further and get involved in it, including making music in mnany cases.

It is no more artificial for deculturated English people to get into Irish music, or blues, or other types of American music such as bluegrass, than for them to seek out ethnic English traditions which are equally alien to them.

Of course some people do do that, and a lot of great music has come out from it, and I'm very glad it happens. But it'd be a nonsense to have people saying "You are ethnic English - you shouldn't be singing the blues or playing slip-jigs, you should be Morris Dancing", or "You are Black - you shouldn't be singing Border Ballads, you should be playing a thumb piano."

Our genes don't determine what kind of music we should play.
