I dont really follow Grand Zaiko Wawa. I know there was a moment that Bongo Wende joined them for a moment after leaving Viva La Musica in 1981 before rejoining Viva La Musica again in 1982 after the split which led to Emeneya, Bipoli and co's departure, to join them in 1984 when Bipoli, Safro and co left to form Victoria Principal and leaving Emeneya alone with his Victoria Eleison.
Maybe that they recorded a version with Bongo Wende or it could be that they interpreted his solo. Because Bongo Wende used to play that sebens already in concerts of Viva La Musica. Congolese bands sometimes plays sebenes who are left by solists in their band. Before that Bongo Wende rejoined Viva La Musica in 1982, he was working for Air Zaire for a moment as mechanic, since that Pepe Felly Manuaku decided to fire the whole band (except Nzenze and Shekedan). Felix wanted musicains who could copy Zaiko Langa Langa. I remember Lidjo Kwempa talking about that in an interview, being still dissapointed about it, feeling like Felix Manuaku saw him as a faux musician.
