By education and occupation I suppose I would be considered and would probably define myself as "middle class" although born and raised in a "working class" family where singing around an old piano on high days and holidays was very much part of our culture.

I regard myself as "left-wing" too as it was the policy of equal opportunities in education that enabled me to make that transition.

It has been my personal experience to find that music and talent has little to do with the "class structure" however we define (or refuse) to define it!
True those who have 9-5 physically undemanding jobs may have more time and energy to relax and enjoy whatever music they prefer most.

btw - are the other 1% Social Workers Les? :)

That's the best definition I've heard yet Folkiedave! LOL!
