aza na raison. That style Philipe Guez created for Koffi on Fouta Djallon and what people are calling nowadays Tcha-Tcho, was already played by Tabu Ley in the 70's. The real Tcha-Tcho, which Koffi is not playing anymore is to find on Spaghetti, Mannequin, Bokilo To Suki Wapi, Tcha-Tcho du Sorcier, Kot Kot & Petit Frere ya Yezu. Ask it Do Akongo, Manu Lima or Rigo Star. They will say that i'm right.
