The main theme that permeates the score was not composed by the film's credited composer, but by Fermo Dante Marchetti, who wrote it in 1932. The melody was the basis for the popular song "Fascination", with English lyric by Dick Manning. The song's copyright was renewed in 1945, and again in 1954. It was used to great effect in the film Love In The Afternoon, resulting in its major success on the hit parade.
This original French-speaking, nonmusical, black-and-white version of "Gigi" is included as a bonus feature on the Warner Bros. 2008 Blu-ray release of the MGM Academy award-winning 1958 musical version of this film.
