You stay off'a my back and I'll stay off'a your back!
When the Enchanted Tiki Room went down in the early Nineties for a refurbishment, its sometimes tolerance-testing 17 minute duration was trimmed to a taut 12 minutes by the exclusion of the peaceful Barcarolle number. Borrowed from Jacques Offenbach's opera Tales of Hoffman, the Barcarolle offered a calming interlude after the explosive introductory song The Tiki, Tiki, Tiki, Tiki, Tiki Room. It was, however, an unspectacular use of the attraction's signature audio-animatronics. Any use of audio-animatronics in 1963 was astonishing, and the Barcarolle served a proper function in the pace of the show, but 30 years later it simply tried the patience of audiences eager to get out and ride the Haunted Mansion or the Indiana Jones Adventure.
A barcarolle is a type of folk song sung by Venetian gondoliers or music in that same style. In Tales of Hoffman, which is regularly described as one of the most popular melodies in opera, the barcarolle is a piece entitled "Belle nuit, รด nuit d'amour" and is sung between the Venetian courtesan Giulietta and Hoffman's muse Nicklausse, disguised as a male companion. In the opera, the pleasant melody underlines something sinister: Hoffman believes that Giulietta is in love with him, but in fact she is seducing him under orders from Hoffman's enemies.
Most uses of the song outside of Tales of Hoffman have employed this contrast in melody and intent. For example, in the film Life is Beautiful (1997), it contrasts the height of European culture with the collapse into fascism. Disney evidently thought that it just sounded nice, and previously used it in the 1931 Silly Symphony cartoon Birds of a Feather.
