Well, I have an opinion:
It should really sound like this: http://media.putfile.com/pirateswav
(Don't pay attention to the talking, listen to the score. It's from "Remember, Dreams Come True" at DLR)...
That sounds like it could fit into the movies somehow...like during a battle scene. I dunno lol
Sorry for the bad quality on that AND: I was just listening to "He's a Pirate" on the COTBP soundtrack and I noticed: If you play the "Yoho Yoho" theme in your head without lyrics and you play it in a low tone and fast, the two sound similar. Just try it O_o lol
