Judging by the comments on the first post of this concert by the legendary Syli Orchestre National from Guinea, there seems to be some uncertainty about the musicians participating.
I am certainly not qualified to express an opinion, but I can try and help. Not just by sharing this video, but also by posting some photos from another version of this same video.
The latter is from a commercial video cassette titled "Justin Morel Junior présente L'Afrique en Fête" (JMJ Video KV 1950). Unfortunately the video shows little respect for the historic value of the images, because it contains more video effects (strange whirls, zooms, cross-fades and such) than clear footage.
And it also breaks off after just over 6 minutes!
So it seems there just isn't any more left of this track than these six minutes and 12 seconds....
But these minutes are precious, as I am sure you will agree.
