Probably best known in the version sung by Frank Sinatra (1915-1998) although recorded by many others, including Elvis Presley and Sid Vicious, the music of the song we know as "My Way" was originally composed for a French lyric by Claude François (1939-1978) and Jacques Revaux (born 1940). The former also sang it. The original title was "Comme d'habitude", which means "in the usual way" or "as ever". It basically, though with Gallic charm and drama, describes the drudgery and routine of every day life.

The Canadian singer and song writer Paul Anka (born 1941) was very taken with the tune, and proceeded to write his own lyrics, which have absolutely nothing in common with the original ones. He claimed to have written it at one take in the small hours. The language is based on the vernacular of the "Rat Pack" as used by Sinatra himself - and it is, indeed, an amalgam of lofty sentiments and slang phrases such as "I ate it up and spit it out".

According to Sinatra's daughter, the singer himself became heartily sick of the song and came to dislike it intensely!
