I don't believe that they will that one day. They are so diffent then the Clan Zaiko & Clan-African Jazz/OK Jazz who were still collaborating which each other despite their rivaleries and problems in their private-life. Fally-fans will never accept a collaboration with Ferre Gola. They will then say that Fally's level is to high to collaborate with Ferre and Ferre will be influenced by his staff to not do that 'eko sopa ye, etc.'. I think that a Wake-Up project will come the day they will be finished like Mbilia Bel and Tshala Muana did last year while people were waiting for a collaboration in the 90's. A legend like Wemba was always collaborating with his old collegues of Zaiko who weren't influent anymore like in the past. But Ferre will never accept to perform with Baby Ndombe, Lacoste, JDT and Japonais on the same stage. Except if they are guests of his concert.
Back in the days they were forcing rivals and new creating bands to perform on the same stage against each other to see who's better (Emeneya vs Papa Wemba, Zaiko vs Langa Langa Stars, etc.). With those artists and bands always accepting it because they didn't want to be seen as cowards. Emeneya used to call Fally, Ferre, JB and Werra babies for being scared to perform against each other on the same stage while he used to perform against Papa Wemba many times and against a legend like Luambo Franco Makiadi.
