Here's a short recording by Theo Loevendie's Consort from Antibes previously offered in some comments or in the contributions section.
It was recorded the same year as the Blue Notes (in Antibes) after they left South Africa.
From both groups there was a french TV footage but apparently it has been deleted from youtube.
Which may not have a whole lot to do with this recording but it seemed like a good place to start....
