1977 · Behind the Songs
The title track in all but name — the purest distillation of the Bee Gees’ disco alchemy.

Of the three Saturday Night Fever singles, “Night Fever” is the most single-minded: a slow-building groove that locks in within seconds and never lets go. Barry Gibb has said the title phrase was a play on the era’s club culture, and the song plays like a thermometer reading of 1977 itself.
The production is famously lush — strings sweep over a rhythm section that barely breaks a sweat, and the brothers’ harmonies stack higher with every chorus. It was the first of the Fever singles recorded, and its drum track became the loop that powered “Stayin’ Alive.”

Released in early 1978, it spent eight weeks at number one in America, the longest run of any Bee Gees single. For two months that spring, you could not turn on a radio without hearing it — and nobody seemed to mind.
Where “Stayin’ Alive” has attitude and “How Deep Is Your Love” has tenderness, “Night Fever” has pure temperature: the sound of a room full of people moving as one. It remains the definitive document of disco at its most euphoric.
