This passed me by. I only had a couple of African singles in '63 - one by Miriam Makeba, the other by a white South African ("Talkin' Joburg blues") whose name I've forgotten - perhaps one or two others, which I've entirely forgotten now. Oh, "Tom Hark", of course.
This looks interesting - the early development of Mbaqanga - if one is interested in Mbaqanga. I suppose I should be, but most of that stuff I've got is from the jazz side - Ibrahim, Masekela, Pukwana, Rachabane, Coetzee, Jansen, Mpale - can't listen to EVERYTHING. (Though I'd like to.)
