From the wiki: “‘Day-O (The Banana Boat Song)’ was originally a Jamaican folk song of unknown title. It was thought to be sung by Jamaican banana workers, with a repeated melody and refrain (call and response); with each set lyric there would be a response from the workers but using many different sets of lyrics, some possibly improvised on the spot.
