<P> Early forms of calypso were also influenced by jazz such as Sans Humanitae . In this extempo (extemporaneous) melody calypsonians lyricise impromptu, commenting socially or insulting each other, "sans humanité" or "no mercy" (which is again a reference to French influence). </P> <P> The first major stars of calypso started crossing over to new audiences worldwide in the late 1930s . Attila the Hun, Roaring Lion and Lord Invader were first, followed by Lord Kitchener, one of the longest - lasting calypso stars in history--he continued to release hit records until his death in 2000 . 1944's "Rum and Coca - Cola" by the Andrews Sisters, a cover version of a Lord Invader song, became an American hit despite the song being a very critical commentary on the explosion of prostitution, inflation and other negative influences accompanying the American military bases in Trinidad at the time . Perhaps the most straightforward way to describe the focus of calypso is that it articulated itself as a form of protest against the authoritarian colonial culture which existed at the time . </P> <P> Calypso, especially a toned - down, commercial variant, became a worldwide craze with the release of the "Banana Boat Song", or "Day - O", a traditional Jamaican folk song, whose best - known rendition was done by Harry Belafonte on his album Calypso (1956); Calypso was the first full - length record to sell more than a million copies . The success of that album inspired hundreds of "Folkies", or the American folk music revival to imitate the "Belafonte style", but with a more folk - oriented flavor . The Kingston Trio would be a good example . 1956 also saw the massive international hit "Jean and Dinah" by Mighty Sparrow . This song too was a sly commentary as a "plan of action" for the calypsonian on the widespread prostitution and the prostitutes' desperation after the closing of the U.S. naval base on Trinidad at Chaguaramas . </P> <P> In the Broadway - theatre musical Jamaica (1957), Harold Arlen and Yip Harburg cleverly parodied "commercial" Belafonte - style calypso . Several films jumped on the calypso craze in 1957 such as Island in the Sun (20th Century Fox) that featured Belafonte and the low - budget films Calypso Joe (Allied Artists), Calypso Heat Wave (Columbia Pictures), and Bop Girl Goes Calypso (United Artists). Robert Mitchum released an album, Calypso...Is Like So (1957), on Capitol records, capturing the sound, spirit, and subtleties of the genre . Dizzy Gillespie recorded a calypso album Jambo Caribe (1964) with James Moody and Kenny Barron . </P>
