Gipson Butukondolo was also messing the chorus many times up. I remember some concert were it was like he was fighting against Lola Muana, about who can the best messing the chorus up hahahaha. The song Nul n'est Parafait during the LSC-concert in 2000 is a good example.
I wonder what made Koffi suddenly sing the song Sens Inverse in concerts, while Do Akongo already left QL.I don't like the live-versions of Sens Inverse, they are always wrongly executed. The same for many Effrakata songs who were arranged by Philipe Guez. Songs like Logique, Babou & Robot.
