This is a unique clip from a tv show on Zairean television called "Tonton Skol". It features singers Carlito Lassan (at the time probably still with the TP OK Jazz) and Dindo 'La Voix Cassée' Yogo (either still with Langa Langa Stars or with Zaiko Langa Langa) in a track composed by Tabu Ley Rochereau when he was singing alongside Kabasele in the African Jazz orchestra. The orchestra accompanying this impromptu duo is Mbonda Africa of Johnny Bokelo (standing on the right playing guitar).
I have always been a fan of Carlito, ever since tracks like 'Maya', 'Affaire Kitikwala", "Bon Samaritain" and "Sisi"*. And Dindo Yogo has popped up regularly as someone I should take more notice of.
Both have disappeared now from the limelight. Dindo Yogo, because he passed away in 2000. And Carlito, because he is now known as Frère Carlito, i.e. -as too many Congolese artists- he has found religion.
There is more information about Dindo Yogo in this great article by Martin Sinnock.
*If you don't know these tracks, let me know and I'll post them.
