Was Bastin in the group yet? Also, was there a mi soloist for their concerts? I noticed they never credited Saint Petro for his role, was he not really official member?

Papy Bastin was already there. He joined Extra Musica just before the split and was recruited long with Papy Jah by Quetin Moyascko. When the band split they were  approached by Quetin to follow him in Extra Musica International, but they refused. It could be that he was either in Brazzaville or Paris with Arafat, it could be that he was part of the trip to Benin, but that they just picked the tracks where he didn't sing, because in this tape they just selected Succes Extra, Losambo and Etat Major. I think that he was there, because if I remember well, he did 10 or 15 years ago an interview to talk about his time in Extra Musica and he talked about a trip to Benin.

Saint Petro joined them, but he didn't last long. When he came for Zenith 2001, he ran away during the tour. It was rare in Extra Musica to see an artist join today and immediately getting space or the chance. Papy Bastin also talked about it and said that he and Papy Jah suffered alot before become part of the 1st team.

The video in reality ends at 45:18 min

I noticed that all videos produced by Jimmy Houetinou of Ndombolo artists performing at Stade d'Amitie (Général Défao, Awilo Longomba, Werrason, Extra Musica and J.B. M'piana) being really short always being either 30 or 45 minutes long. I wonder if it's due to his videos being collaborations with the LC2 one of Benin's national tv channel.
