Jon & Vangelis is the collaborative effort between the singer Jon Anderson (better known as lead vocalist of the British progressive rock band Yes), and the Greek synthesizer musician Vangelis. Together they released a number of successful albums in the 1980s. The two artists probably met in the progressive rock scene of London in the 1970s. Vangelis reputedly was to join Anderson in Yes, replacing Rick Wakeman as keyboardist, but this never came to fruition. Nevertheless, Jon contributed vocals to Vangelis' Heaven and Hell (1975), harp to Opera Sauvage (1979), and vocals to See You Later (1980).
