This song, "Kabambare" composed by singer Papy Tex and performed by him with Pépé Kallé and Empire Bakuba was released in 1985 on the album of the same title. But to be honest the album version can only be described as 'anemic' in comparison to the superb full-blooded version in this video. And this is mainly due to the technical imperfection of this recording, and in particular the balance between vocals and supporting instruments.
I add that in general I am not a fan of Empire Bakuba, let alone an expert on the group. But this video is official and irrefutable proof of the vocal talents of Papy Tex, Dilu Dilumona and Pépé Kallé, both as individual vocalists and as a harmonic trio.
It explains too why Franco was desperate to have a Pépé Kallé voice in his orchestra (see this post)...
EDIT September 12, 2015: I have mixed up the two songs of this video. The song you find above is "La Terre Sainte", and the one I have added below is "Kabambare". This song too demonstrates the vocal talent of the singers of Empire Bakuba, and adds to my point that these live versions are more interesting than the studio version.
"La Terre Sainte" (the holy land) is composed by a certain Dadou; and this is probably not the Dadou of the songs with this title.
