The band was releasing an average of four albums a year during this period. The rival Congolese bands, Afrisa International and Orchestre Veve could not keep up with the competition. Life was good. In 1982 Sam Mangwana returned briefly and released an album with Franco called Cooperation. Franco also released several albums with former nemesis Tabu Ley. In 1983 TPOK Jazz toured the United States of America for the first time. That year the song "Non", featuring Madilu System and Franco in alternating lead vocals, was released. In the mid-1980s the band continued to churn out best sellers including Makambo Ezali Borreaux, 12,600 Letters to Franco, Pesa Position, Mario and Boma Ngai na Boma Yo. By this time, Madilu System had taken over as the lead vocalist. In 1986, Josky Kiambukuta and Zitani Dalienst Ya Ntesa, two vocalists who felt they were not getting enough prime time exposure led another mass exodus to form their own band. Around this time, Simaro Lutumba released an album outside the OK Jazz system, featuring the song "Maya". During the same timeframe, Malage de Lugendo, a vocalist, was recruited. Also Kiesse Diambu ya Ntessa from Afrisa and female vocalist Joliet Detta came on board. At the beginning of 1987, Franco released a 15-minute song with the title "Attention Na Sida" (Beware of AIDS). Sung mainly in French amid heavy African drums and a kaleidoscope of thundering guitars, the song is moving even if one does not understand all the words. Also in 1987, TPOK Jazz were invited to perform at the 4th All-Africa Games in Nairobi, Kenya. On one of the eight albums that the band released in 1987, called Les On Dit, Franco introduced two new female vocalists Nana Akumu and Baniel Bambo. In 1988, Josky and Dalienst re-joined the band. 1989 was a challenging year for the band. Franco's health was in obvious decline. He had by now moved permanently to Brussels. He did not play much and when he did, could only manage about twenty minutes. The band started to fall apart with the defection of Malage de Lugendo and Dizzy and Decca, who returned to Kinshasa to pursue other opportunities. Later that year Sam Mangwana teamed with Franco to release the album Forever. The album sleeve carried a photograph of Franco in which he appeared emancipated and obviously in ill-health. It turned out to be Franco's last album. On 12
