"'La vie en rose' (French for "Life in pink") was the signature song of French singer, Édith Piaf.

Piaf first popularized the song in 1946. The lyrics were written by Piaf and the melody of the song by "Louiguy" (Louis Gugliemi). Initially, Piaf's peers and her songwriting team did not think the song would be successful, but it became a favorite with audiences.[1] An English version of the lyrics was written later by Mack David. Owing to its popularity, the song appeared on most of Piaf's subsequent albums. A 1998 documentary about Édith Piaf was called La Vie en Rose, as was the 2007 biographical feature film La Vie En Rose, which won Marion Cotillard, who played Piaf, an Oscar as Best Actress.

The song has become a standard and has been performed by many artists. It was given a Grammy Hall of Fame Award in 1998. It has also become a generic song representing the French, as Rule, Britannia! and Stars and Stripes Forever have for Britain and the US, respectively." -Wikipedia
