General Defao reveals here that he came with the Bana Congo-concept because of the Wenge-split and that Pepe Kalle also had to sing, having even a cassette of the song he had to sing at home, but he died before on Tuesday while they had to record the song on Wednesday. JB Mpiana had also to sing on that album, but he didn't sing (I guess that he refused after hearing that Werrason already sung).
Also saying that he starts touring in Kongo Central before performing in Kinshasa and why they started the tour there (governor Atou Matoubuana is suspend for the Mimi-affaire, so I don't if he will finish the tour. He has to perform in Matadi today). It reminds me of the way Papa Wemba started performing in Matadi back in 1984 after spending 8 months in Europe before giving his first concert in Kinshasa.
They recorded the interview at Village Chez Ntemba where they were rehearsing for the conerts.
