On this day in music, 1978, the Bee Gees begin a 24-week run at #1 on the US Album charts with the soundtrack to the movie "Saturday Night Fever". Both the movie and the album sparked huge interest in the disco movement, not only in the US, but around the world.
The album featured four #1 singles; three by the Bee Gees ("How Deep Is Your Love?", "Night Fever", and "Stayin' Alive") and one by Yvonne Elliman ("If I Can't Have You").
The album, produced by Giorgio Moroder, would go on to sell over 15 million copies and become the highest-selling soundtrack in music history - that is, until "The Bodyguard" soundtrack surpassed it in 1992.
