"Someone Saved My Life Tonight" is an Elton John song from his album Captain Fantastic and the Brown Dirt Cowboy. It is written in the key of A-flat, though after having vocal cord surgery in 1987 that resulted in the loss of his falsetto range, John began performing the song in the key of G. As of 2009, he has been performing the song in the key of F. It concludes side one in the album's narrative of the history of John's and lyricist Bernie Taupin's struggles to find careers within the music industry. When released as the album's only single in 1975, it reached #4 on the Billboard Hot 100 and entered the top 25 on the UK Singles Chart.
Taupin's lyric refers to a time in 1969, before John was a popular musician, when John was engaged to be married to his girlfriend, Linda Woodrow. John and Woodrow were sharing a flat with Taupin in Furlong Road in the East End of London, hence the opening line "When I think of those East End lights." While having serious doubts about the looming marriage, John contemplated suicide. He took refuge in his friends, especially Long John Baldry, who convinced John to abandon his plans to marry in order to salvage and maintain his musical career. As a sign of his respect and gratitude for Baldry, Taupin wrote him into the song as the "someone" in the title. Some radio stations banned or altered the song, due to the use of the words "DAMN IT" in the second verse.
