Which song was used to open and close the 1958 film "Gigi"?

"Thank Heaven for Little Girls" is a 1957 song written by Alan Jay Lerner and Frederick Loewe and associated with its original performer, Maurice Chevalier. It opened and closed the 1958 film Gigi. Alfred Drake performed the song in the 1973 Broadway stage production of "Gigi", though in the 2015 revival, it was sung as a duet between Victoria Clark and Dee Hoty.

The Chevalier version is often regarded as the definitive version of the song; he recorded it in 1958. In 2004, it finished at #56 on AFI's 100 Years...100 Songs survey of top tunes in American cinema.

In the mid-1990s, a contemporary take on the song was recorded by the Seattle-based alternative band Ruby for a Mountain Dew commercial in the United States. This recording was later repurposed by PepsiCo for their Pepsi Max brand in the UK.

Bing Crosby recorded the song for his radio show in 1960 and it was subsequently released on the CD Songs "I Wish I Had Sung the First Time Around" (2014). It has also been performed by Rosemary Clooney, Perry Como, Gérard Depardieu, Merle Haggard, Hugh Hefner, The King Brothers, Ed McMahon, and in his faux French accent, Peter Sellers. In the "Happy Days" Season 5 episode "Be My Valentine" (February 14, 1978), a then-18-year-old Scott Baio sang it as part of a series of musical numbers commemorating Valentine's Day. In the 1997 film "Wag the Dog", the song performed by Chevalier is used as backdrop for an election campaign ad.
