The song was originally written by George Bruns, a composer for Disney films, and Imagineer Xavier Atencio.
In The Curse of the Black Pearl, Elizabeth Swann (Keira Knightley) and Jack sing this song while stranded on a deserted island. Jack also utters the phrase “Drink up, me hearties, yo ho” at the end of the movie. It’s used in some way in every movie to pay homage to the classic attraction.
