Waliou Jacques Daniel Isheola "Wally" Badarou (born 22 March 1955) is a French-born musician. A synthesizer specialist, Badarou was the long-time associate of the British band Level 42, known for its blend of funk, pop, soul and rock. He has co-written and performed on a number of the band's tracks since their recording début in 1980, later co-producing them. Though not an official member of Level 42, he has long been considered an informal "fifth member"[citation needed] of what has otherwise usually been a quartet with bassist Mark King
