Space - Magic Fly

Space disco never really took off as a genre, but French band Space and their instrumental single "Magic Fly" became a huge hit in 1977. Incredibly their first three albums, released in 1977 and 1978 sold more than 12 million copies, according to a Wikipedia article. They released a fourth album in 1980 before disbanding. "Magic Fly" still sounds great, and the video is hilarious, definitely a product of its time.
