A few days ago, I was listening to some Wenge. I took a close look at the Kin e Bouge cover and noticed handcuffs on the band. Until that point, I thought they were just posing. Does it have something to do with the time they went to prison, hence some of the lyrics on the title song?

yes,jb and marie paul created  some parts of the song when they got arrested,the rest of the original song got sung way after in no comment schengen
