No sign of Roberta Flack on DVD or the accompanying soundtrack CD, but as I don't particularly rate her that's no problem. Very enjoyable and joyous clash of cultures. My brother was living and teaching in Ghana at the time and was at the concert, now I've got an idea of what it was like. Great footage of Ike & Tina Turner and the Ikettes in their prime, lovely to see Tina T getting a singing lesson in the street (she does well !).
WARNING: the DVD is in NTSC format, make sure your system can cope.
