Thanks for the heads-up MoeJoe.
It's not just world music; I'm browsing the archives of the St Mary-le-Bow public debates - fascinating stuff I never knew existed!
Update: Drat! can't actually play the debate recording unless you're from an educational institution. I hadn't ticked the 'Only recordings everyone can play' box.
Instead I'm listening to "
East Poland soundscapes: A hot afternoon on a boggy heath near Urszulin." Is that a yellow bunting? Yes, I do believe it is.
