LOL you really believe that? ferre himself said later that he was losing his voice easily because his voice was not mature enough and he lacked stamina when singing several songs,i think he said that in the context of the tense bcbg maison mere war
in bcbg somebody also did that sort of claim in those days,tutu i think or aimelia
if aimelia had sung in th you would have seen him counter attacking ferré in interviews(instead of jb,you know the usual strategy of leaders,except koffi,to let the "soldiers" do the dirty job)
