From Wikipedia:
"Tico-Tico no fubá" (Brazilian Portuguese: [ˈtʃiku ˈtʃiku nu fuˈba]; "rufous-collared sparrow in the cornmeal") is a Brazilian choro song written by Zequinha de Abreu in 1917. Its original title was "Tico-Tico no farelo" ("sparrow in the bran"), but since Brazilian guitarist Américo Jacomino "Canhoto" (1889–1928) had a work with the same title, Abreu's work was given its present name in 1931, and sometime afterward Aloysio de Oliveira wrote the original Portuguese lyrics.
Outside Brazil, the song reached its peak popularity in the 1940s, with successful recordings by Ethel Smith, The Andrews Sisters (with English-language lyrics by Ervin Drake), Carmen Miranda and others.
From IMDB:
* At the time of its release, this was MGM's third-highest grossing film, after Ben-Hur: A Tale of the Christ (1925) and Gone with the Wind (1939).
* The movie was initially to be titled "The Co-Ed" with Red Skelton having top billing. However, once MGM execs watched the first cut of the film, they realized that Esther Williams' role should be showcased more, and so changed the title to "Bathing Beauty", giving her top billing and featuring her bathing-suit clad figure on the posters.
* While filming at Lakeside Pool on a cold January day, the swimmers went on strike unless director George Sidney stripped naked and went into the water.
