the whole fake persona of anglo folk was everywhere back in the sixties and seventies. it's cultural appropriation. a form of racism. it's often worse from old "socialists". their brave new world of fine housing would have happily wiped out the ethnic enclaves, and not to worry about the culture, they would do the culture for you.
jimmy miller wrote good songs, but he was unconscious of the effect of his ideas about ethnic differences. his followers pretty routinely would shut out people actually from the ethnic background he pretented to be from because they had one of those--a fake. I found this for French gaelic and many other ethnic groups.
it's so much easlier to have a well mannered anglo sing the foreigh songs than those annoying foreigners who don't know who to brown nose and how to tug the forelock properly.the anglo folk scene is much more concerned with minorities kissing the right asses than the actual music. luckily the paying scene wants traditional music played by people from traditional cultures--especially in the united states.
and miller was from lowland scots background. NOT A GAEL. the reason lowland scots and English want to pretend these ethnic differences don't matter is because then they would have to address their centuries of bloodshed and injustice. after all it's all just geography, I was born in nova scotia so I an an Amerindian native , that would be the same claim.
