Leilani "Lani" Hall (born November 6, 1945) is an American singer. From 1966 to 1971, she performed as lead vocalist for Sérgio Mendes & Brasil '66. In 1972, Hall released her first solo album, Sun Down Lady. She may be best known, however, for providing the most recognisable female face and vocal signature sound to Mendes's group during her tenure there, and for her rendition of the theme song to the 1983 James Bond film Never Say Never Again, with its accompanying video, in which she prominently appears.
