@7:31 When Fally finished his part in Inchallah it was time for Junior to do Bouro's vocal and when Junior was in the middle of singing, Fally just abruptly cut him off. Koffi didn't even give the ok to go for a second time. I can tell the crowd was still excited for Fally but he could of sand it again immediately after he was done the first time and not looking rude in the process.     

These things happen all the time on stage,he was wrong to cut him off the way he did but am sure he was just responding to the paying customers who wanted him to repeat the line of lyrics,am sure Junior Embroille got his time to shine after since the song doesn't stop there.
