Stayin' Alive
The Bee Gees wrote 'Stayin' Alive' for a Saturday Night Fever script they hadn't read yet, and the drum loop underneath it exists because the actual drummer couldn't make the session.

Greatest of All Time!The Bee Gees wrote 'Stayin' Alive' for a Saturday Night Fever script they hadn't read yet, and the drum loop underneath it exists because the actual drummer couldn't make the session.
Robert Stigwood, producing a film then called Saturday Night, asked the Bee Gees for songs based on a synopsis alone – the brothers wrote “Stayin’ Alive” and several other Saturday Night Fever tracks without having seen a script or a frame of footage, working from a description of a Brooklyn disco kid and little else. The title phrase, according to the band’s later interviews, came out of Robin Gibb almost as a throwaway, and it ended up carrying the entire message of the film back to the audience: a song about survival set to a beat built for dancing.
The beat itself is a famous accident. Drummer Dennis Bryon couldn’t make the session because of a family emergency, so producers looped a two-bar drum break from an earlier Bee Gees track, “Night Fever,” and built the rhythm track around that loop – a sample technique years before sampling was a recognized production method. That looped bar is why the drums sit so hypnotically steady under Barry Gibb’s falsetto; it’s a machine-precise foundation built from a human performance repeated until it stopped sounding like one.
“Stayin’ Alive” spent four weeks at No. 1 in early 1978 and the soundtrack went on to become one of the best-selling albums ever made, turning three brothers who’d spent the mid-1970s commercially adrift into the defining sound of an entire genre’s commercial peak. Greatest of All Time.
