yes afande had serious serious flu,if i remember well titina also or ficarre was also very sick the day of concert and i remember before the concert some people were announcing it that they will be "weakened" a bit like how in african football people do juju to make the opposition attackers drop a massive stinker of a match if possible the guy was later in the day easily taking "care" of two of his sidekicks he had who paid rooms at a big france hotel like nothing happened
and yes it was probably the most stressful of the bercy's,it was organized mainly by the fans until badive stepped in then backed out after threats then stepped in then backed out,then they struggled for plane tickets,and what people do not know aswell was that there was a first attempt of one of the two three parts of the delegation which had guys whose passeport was suddenly showing another face and they were not allowed and had to be piled up along with the original second delegation and ngulu's,but now they had to find a plane to fly all together
i dont know how true it is but at some point the concert could have faced cancel at last minute because of calls,i gotta ask my brother
