Aaaagh! So sorry Will! I didn't see your thread before posting mine!
It's just finished. Terrific stuff.

I'd never heard that song 'Have A Whiff On Me' about a cocaine habit!
And those brave and tough Appalachian people who travelled miles to be recorded on the new-fangled recording machines (wax discs) Such poverty but such spirit.
It was interesting to hear the roots of modern music (rap for example)
and origins of blues from Gospel music.
I'm terribly ignorant about these genres, and wish the programme had been twice as long!
