I'll translate based on memory as i watched it long time ago but just forgot to post
in short he says its true that their promotion of libre parcours was not good enough and admits they got a bit complacent seeing how great their leader is and thought being his musicians would be enough to automatically promote album
 he says maybe one day he will do a solo album(as he is a writer) but for now he has a song and he is grateful for that,he is been close to fally for 16 years and he can say his life has changed a lot next to fally even though there is still a long way to go
 he says jb,werra,kabose,lacoste,their"grandfather" koffi,fabregas all do some proper music and he surprises presenter by mentioning ferre aswell and adding "jesus de nuances"like he is called by fans,and  reveals that he has no problem at all with ferre he is a band president so he deserves a lot a respect and says he's witness fally abd ferre's common time in quartier latin as he was very often at rehearsals with them and he did not see tham have  any problem
he also talks about heritier saying he is a good artist and he will listen to his album when its out

He's a waste of space as a singer in F'Victeam, he inconsistent there's times he sings good and other times he doesn't. There are way better singers then him. And another thing, it's always Ferre's people who have a complex attitude towards Fally and his people.

What hits did Tony write for Fally to keep him that close?

it's always Ferre's people who have a complex attitude towards Fally and his people.

It's called polemique and nothing to do with complex,it is strategy to keep other in the news and it pays massively, both bands appreciate that, even the recent Sankara vs Werra or now Heritier vs Werra, it's all polemique, they all know what they are doing so don't follow blindly and start hating for nothing, these chaps meet at home and eat nguba whilst drinking masanga ya mbila together however it's undeniable that Ferre's singers are more known and are better singers and dancers and have more swag than Fally's musicians some who are well older than Fally.

What hits did Tony write for Fally to keep him that close?

too many,and yet to be released well,but among the released there is for example tsho or deliberation and also he would sometimes modify lyrics from other writers to adapt to something which "sounds like fally"
