Following the Nigerian Civil War in the late 1960s, the massive exodus of the eastern peoples of Nigeria (especially the Igbo) out of western Nigeria had caused the death of the Highlife's prominence in the then capital, Lagos. During the war and after the war Osadebe maintained his scheduled live performances. Jùjú music and later Afrobeat took precedence in Lagos, and in the 1970s James Brown and various other music forms became popular in the city. In this same decade, Osadebe's career had reached its zenith. After turning 50 in 1986, Osadebe started to give priority to fatherhood and gave more of his time to his son Obiora and his other children from his wives. One of Osita Osadebe's last albums is "Kedu America".
