from 16th  minute he talks about his friendship with jb who used to invite him a lot at  wenge 4X4 and early bcbg concerts

So he was to sing Feux de l'amour with Jb? What happened??

 Jb changed mind after doing feat with bokul i think he only wanted one feat on album so when papa wemba accepted he gave priority to him obviously as his idol he proposed feux de l'amour and cavalier solitaire and papa "felt" cavalier more
