http://en.wikipedia.org/wiki/Rum_and_Coca-ColaAlthough the song was published in the United States with Amsterdam listed as the lyricist and Jeri Sullavan and Paul Baron as musical composers, the melody had been previously published as the work of Trinidadian calypso composer Lionel Belasco on a song titled “L'Année Passée,” which was in turn based on a folksong from Martinique.[2] The original lyrics to “Rum and Coca-Cola” were written by Rupert Grant, another calypso musician from Trinidad who went by the stage name of Lord Invader.[3] (The true credits for music and lyrics were restored in a plagiarism lawsuit won by famous attorney Louis Nizer, the account of which can be read in his book, My Life in Court.)
According to Lord Invader, “Calypso is the folklore of Trinidad, a style of poetry, telling about current events in song. Back home in the West Indies, Trinidad, where I'm from, it's a small island, I'm proud of it. I was traveling on a bus, someplace they call Point Cumana, a bathing resort, and I happened to see the G.I.s in the American social invasion in the West Indies, Trinidad. You know the girls used to get the candies and stuff like that, and they go to the canteens with the boys and so on, have fun. So I noticed since the G.I.s came over there, they really generally chase with soda, ordinary soda, but their chaser was Rum and Coke. They drink rum, and they like Coca-Cola as a chaser, so I studied that as an idea of a song, and Morey Amsterdam had the nerve to say that he composed that song back here.”[4]
