On Stranger Tides - The Foutain of Youth (Film Score Version) 

This is the film version of The Foutain of Youth (when they enter into the FoY set). It's from the leaked additional score from Geoff Zanelli's website.
Geoff Zanelli is one of the most important co-composer of the Pirates movies, if not the most, since he's the only that has contributed on all of them. He created Tia Dalma/Calypso's theme and the Spanish theme. He also wrote some of the most iconic cues, like Barbossa Is Hungry, Swords Crossed, Diner Is Served, Tia Dalma, Calypso, On Stranger Tides, Palm Tree Escape and End Credtis. Finally, he's the one that arranged He's A Pirate, taking themes from Klaus Badelt and Hans Zimmer.
