Yeah, because Soki Vangu made Viva La Musica really exist and surive in the first days. Back in the days it was impossible to perform if you hadn't instruments or financial support. In that era bands were performing every weekend in bars and clubs. Soki Vangu was their only big donor. But I remember that Papa Wemba a little bit looked irritated on tv when he was interviewed along with Soki Vangu before Viva's first show. This was because Soki Vangu was calling Wemba every time "petit", when he was referring to Wemba after that he journalist asked him why he decided to support him.
pPapa Wemba paid tribute to people like Pecho wa Ngongo, Bayern de Munich, Shaguy Sharufa ,etc. in the song Foridoles. Because they were the people who founded Viva La Musica. Papa Wemba wasn't even interested to found his own band, after getting fired by Mbuta Mashakodo and Mavuela Somo from Yoka Lokole. Papa Wemba thinking of rejoining Zaiko or Isifi Lokole of Evoloko. He even rehearsed with Evoloko in Yolo, while his friends were recruiting musicians. It was because of pressure from his friends that he accepted to have his own band.
