I dont remember if it was Jimmy Mbonda or Bidjana. One of them said that Gentamicine already went for a test along with guys like Strely Mikobi, Spino la Djatence, Soleil Wanga, Fally Ipupa, Chai Ngenge and co at Studio Bobongo when they came back from Abidjan. But Gentamicine not being accepted at that time. Gentaminice being lucky that he got introduced by Tutu Kaluji a few weeks before Zenith when the late Simon Ndjonang came to visit BCBG at Base Kamina to watch if they well prepared for Zenith. Whole the band, admin and fans being amazed for his cri "Ma nsimba kolele nsiama" and immediately being accepted in BCBG.
Celeo had a similar story. According to him, he tried his luck seeing that Tutu Kaludji was suspended during the Pentagone-era. He came to a concert of Wenge at the fancy fair of Salongo. The public and both JB & Werra accepting him. But Mbuta Kis blocking his integration, saying to Celeo that he has to write a letter and that he would contact him afterwards, which never happened. Only atalaku close to join was Mboshi Lipassa. Werrason already knew him and wanted him to replace Tutu Kaludji (who was indirectly fired, but didn't understand it). However, Koffi was quicker and recruited him the day Werrason had to present him to the public as new member.
