If I'm not mistaken, wasn't Japonais supposed to have a song on A La Queue Leu Leu? Also, what was going on with the keyboard section? Thierry Synthé was around after Les Marquis, but he got sidelined for Rubain Synthé and both were gone by Temoignage. What's the story?
I don't know. But Japonnais himself repeatenly claims it in different interviews, that they recorded a song, but that it got removed when they did the mixing, because of him running away. Also that the song was the first part of Ferre's song Mercure, but at that time dedicated to Annie Ntimambote. But what I don't understand is that he said in different interviews that he ran away on the last minute, when the group was about to return back to Africa. This made me wonder if is his story is true, because bands do always the mixing before returning back to the country, so how could they have removed the song if he was still there on the moment.
In one of those interview Japonais explained that when the tour ended, he ran away on the last minute when Werrason was about to take the flight with the rest of the band to Angola, before returning to Kinshasa. Adding that he requested a payment in order to come to the airport, being fed up to struggle in Kinshasa without money. At the same time Werrason really counted on him, since that they knew that Mimiche would stay and that he (Japonnais) was supossed to do the role as bassist in those concerts, having also paid a new bass-guitar. Him (Japonnais) requesting payment first on the phone, made Werrason mad and insulting his mother. Japonnais staying in Paris with the bass-guitar
I don't know the reason why Thierry Synthé got sidelided. It will only get known if he will reveal it himself in an interview. Maybe a 12 for being suspected of being close with Les Marquis-guys. Flamme Kapaya himself said once that Werrason saw him as a traitor despite staying with Maison Mère, after the creation of Les Marquis. It would not surprise me if he was thinking the same of Celeo, Thierry and the rest. Wenge Maison Mère also adopted the system of Wenge BCBG of playing with two keyboard-players in concerts. If you look at Double Zenith, you'll see them playing with two keyboard-players (Thierry Synthé and Patrick Synthé who ran away after the event). After the creation of Les Marquis, Chevignon Synthé of Operation Dragon (second team of Maison Mère) also in. I don't remember if they travelled with two keyboard players during the 2005-europe tour, but Ruben Synthe ran away on that tour. Thierry decided to join his friend Bill Clinton in Les Samourais to return back to Maison Mère in 2009
