Thanks for your response, Gwen. Also thanks for including names and genres of artists.

With regards to Hugh Masekela, I had the pleasure of hearing him live at a nightclub in New York City around 1967. He was 'substituting' for Miriam Makeba who was ill. I've been a fan of Hugh Maskela's ever since.

I noticed that you didn't include Miriam Makeba in your comments. Isn't she still actively recording and performing?
