Here is askin bass who just left kabose's group and in the past was shortly with ferre but he was not getting along with mabuma because of his previous interviews where he was attacking the other bassists of their generation "to  be a soldier of his boss" and after his test he never got to play even in rehearsals for 3 month and left when mabuma was promote to chef d'orchestre role after ruth nzele's transition
and he is saying that mabuma has been fired from ferre's group after getting a dancer pregnant
mabuma has been replaced of late by his backup mukinza na basse ( what a nickname lol)

So can he rejoin Ferre's group?

Wow that’s a ridiculous reason to sideline a good musician and key member of your band. Lol Mukinza na basse is a funny name but I think he played on either the whole or some parts of Boss as Bercy mentioned him @5:06
