The first Syli Orchestre National

Graeme Counsel has sent me three photos of the first Syli Orchestre National, which I would like to share with you. He is trying to identify the musicians in these photos.
Some of these have already been named by Balla (of Balla et ses Balladins), but others remain a mystery.
Honoré Kopé should be Honoré Coppet, a musician from Martinique, who we suspect to be the star of biguine music from the 1940s and 1950s, and who had his own orchestra in Guinea in the early 1960s.
Sanoussi Kanfory was the first chef d'orchestre.
The sax player next to Honoré Coppet has been identified as Mamadi Kourouma.

If anyone can help, please comment on the post or mail to Graeme.
