Mercer and Mancini wrote the song for Audrey Hepburn to sing in the film Breakfast at Tiffany's. The lyrics, written by Mercer, are reminiscent of his childhood in Savannah, Georgia, including its waterways. As a child, he had picked huckleberries in summer, and connected them with a carefree childhood and Mark Twain's Huckleberry Finn. Although an instrumental version is played over the film's opening titles, the lyrics are first heard in a scene where Paul ''Fred'' Varjak (George Peppard) discovers Holly Golightly (Hepburn) singing the song, and accompanying herself on the guitar, while sitting on the fire escape outside their apartments.
