Miracles would have been definitely a banger if Bill, Ferre and Jus d'Ete didn't leave. However, I think that in this video, Gauthier Mascotte was listening to the CD of one of Maison Mère's concerts in Kinshasa, just as people used to have different CDs and audio-cassettes of concerts held in Kinshasa. I used to have a copied CD at home of Werrason's concert in Masina of 2003 (I think I may still have it at home, but I am not sure). I also had a CD of one of Werrason's concerts in Angola in 2002 with Bill Clinton animating Lumumba (the one that he used to do at Madeleine 2002), before the concert at Stade des Martyrs.
I don't believe that it was an extract of Miracles-generique, because at that time they didn't start recording yet and also Werrason was busy to find producers for his solo-album as Jean Pierre Saah's label JPS Production closed. Ir was Celeo who used to do the cri of the "payez, plier plier" during concerts. He used to talk about it often in interviews, explaining that it was one of the cri's he would do in Miracles. Bill Clinton was often doing the "Kimbongila", "Yo tein" and "Ba Yankee bayaka na kundu" cri's.
If you listen well to the drums of Kakol from that sound, you will hear that the audio is from a concert
