“Tragedy” appeared on the Bee Gees 1979 album Spirits Having Flown. The track went to #1 on the Billboard Hot 100 and the UK Singles Chart along with top spots in many other world charts. Though not originally in Saturday Night Fever, it has subsequently been added to the musical score of the West End version of the movie-musical. The song knocked “I Will Survive” by Gloria Gaynor off the top spot in the U.S. for two weeks before that song again returned to number one for an additional week. In 1998 the song again reached the top of the UK singles chart, this time in the form of a cover version by Steps. In 1979, NBC aired The Bee Gees Special which showed how the sound effect for the explosion was created. Barry cupped his hands over a microphone and made an exploding sound. Several of these sounds were then mixed together creating one large boom heard on the record.
