When guests on the original Pirates of the Caribbean attraction at Disneyland Park transition from the skeleton-laden epilogue to the flashback to buccaneers in the flesh, the first scene they encounter is a seige from Captain Barbossa on a coastal fort.  Captain Barbossa is looking for Jack Sparrow, and this hardy edifice is the first barrier in his way.  In the following scene, it seems the seige was successful, because the pirates have no invaded the central town on Isla Tesoro and taken the townsfolk hostage--torturing some by dunking them in the local well and seizing their assets in other cases.  That's what pirates do, though.  These just happen to also do it to a catchy song!
