Les Wanyika was a prominent band with Tanzanian and Kenyan members and was based in Kenya. It was formed in 1978 when guitarist Omar Shabani, bassist Tom Malanga and two other members left Simba Wanyika. They were joined by John Ngereza and Issa Juma. Les Wanyika made many popular recordings, but are best remembered for their 1979 classic Sina Makosa and Paulina. Vocalist Issa Juma left the band soon afterwards to concentrate on other musical projects. The group continued until Omar Shabani's death in 1998. John Ngereza died two years later.
