He was mad because Ngossanga "stole" Mbilia Bel of him and made of her his second wife. It's been said tht when Mbilia Bel left Afrisa after the concert at Palais du Peuple, they went to Brazil without her and Tabu Ley not going outside his hotelroom, being alone and crying every time. He went only outside the hotelroom the moment he had to perform.
Tabu Ley would later sing C'est Comme Ca La against her (The song makes me always sad when hearing it). I don't remember if it was before or after Mbilia Bel's Phenomene where she attacked Tabu Ley.
