This track plays when Guybrush enters the Voodoo Shop on Mêlée Island. It also plays shortly after preparing some weird voodoo concoction that ends up directing Guybrush's ship to Monkey Island. For those who have watched the Pirates of the Caribbean movies, you may notice that there is also a mysterious Voodoo Lady just like in Monkey Island - both with very similar accents and both with hidden agendas. Okay they do look a bit different (the one in the games is big-boned) but then there are also a lot of other similarities between the game and the movies (e.g. a zombie pirate, a wannabe pirate for a protagonist, a love interest born into wealth, etc.). Is there a reason for this? Well there was apparently this claim by artist Steve Purcell :
The really interesting thing is that the movie was going to be produced by Steven Spielberg (who is a big Monkey Island fan himself). He asked Ted Elliott, a script writer who has worked on several Disney movies (including 'Treasure Planet') and on 'Steven Spielberg’s Director's Chair' game, to help with the story for the MI movie. The Monkey Island movie never got the green light and years later Ted Elliott wrote 'Pirates of the Caribbean: Curse of the Black Pearl', which took several ideas from Monkey Island. So basically the first two PotC movies are the Monkey Island movie.
However, a scriptwriter who often collaborates with Ted Elliot called Terry Rossio denied any connection:
Ted Elliott was never hired to write a story or screenplay to the computer game Monkey Island, not in the year 2000 or any other year. Ironically, the creators of Monkey Island have acknowledged their inspiration and debt to the Pirates of the Caribbean ride.
Thanks to the Monkey Island Wiki for the interesting info.
