The Bee Gees' 'Stayin' Alive' is the definitive anthem of the disco era. Written for the 'Saturday Night Fever' soundtrack, the song's steady beat was actually created using a 'drum loop'—a revolutionary technique at the time. When their drummer had to leave for a family emergency, the band took two bars of a previously recorded drum track and looped them manually to create the song's relentless rhythm. This loop became so famous it was later used in numerous other songs. Beyond its musical impact, 'Stayin' Alive' has a unique medical legacy: its tempo of 103 beats per minute is the ideal rhythm for performing chest compressions during CPR. The American Heart Association has even used the song in training videos to help people keep the correct pace. The track remains a cultural icon of 1970s New York City and the peak of the Bee Gees' career.
