Well of course if I used class as a label, I would say that the UK folk scene is Middle Class, and left wing.
The only working class people I ever met, told me they were! Funny how ALL of the people who have described themselves as working class, have held down middle class jobs, and led fairly affluent lifestyles.
I suppose it's only when you reach such a state of financial security, that you can boast about being working class?
