lobby scene. "Funiculì, Funiculà" is whistled by the Streisand character as she crosses the street, following the pizza delivery man, into the Bristol Hotel before the first hotel lobby scene. About two-thirds of the way into the film, Howard accompanies Judy at a piano (on a floor of the Hotel Bristol apparently under construction or renovation) as she sings the beginning of "As Time Goes By" (made famous in the film Casablanca). The scene includes Streisand imitating Humphrey Bogart with the line, "Of all the gin joints, in all the towns, in all the world, he walks into mine. Play it, Sam." Musical in-jokes appear throughout the film. Over-the-top Muzak-styled elevator music featuring Cole Porter's songs is used throughout the hotel elevator scenes. In the chase scene, a Chinese marching band is inexplicably playing the Mexican tune "La Cucaracha" (although, in certain prints, it sounds more like "Deep in the Heart of Texas") on German glockenspiels. At the American Musicologists' banquet, themes from Thoinot Arbeau's Orchésographie can be heard in the background, incongruously played on a Hammond organ and a sitar. George Gershwin's "Someone to Watch over Me" is whistled by Streisand outside the hotel drug store. The Bugs Bunny number—derived from his characteristic tagline—that gives the movie its title appears as well, with the original animation, in the last scene. Instrumental versions of "Please Don't Talk About Me When I'm Gone", an old Tin Pan Alley hit which had appeared in Looney Tunes cartoon One Froggy Evening, are background music during the opening scene in the airport. However, as with Bringing Up Baby, all the music is diegetic—there is no underscoring anywhere in the film. Release The film opened at Radio City Music Hall in New York City on March 9, 1972.
