This is a video of the Harp Twins Camille and Kennerly dressed as Rikku and performing a medley of Final Fantasy songs in what appears to be paradise. Man, I bet there is some GOOD pirate treasure buried in the area. Also, I may or may not have seen a mermaid playing in the ocean behind them during one their closeups. SPOILER: I didn't. Would have been cool though.
Hit the jump for the kind of music I'd love to fall asleep to instead of the usual motorcycles and gunshots.
Thanks to Anita, who agrees Camille and Kennerly may in fact be sirens trying to lure sailors to their untimely deaths upon the reef.
