Okay, "everything's gonna be alright" was performed by sweetbox but by the singer tina harris. later she was replaced by Jade Villalon. Jade sung the final fantasy songs as it says on the game. But Jade Villalon sings english songs but sweetbox is based in korea or something it really dosen;t make sense, she just sings for the english speaking people over there i guess, but her cd's can be found in american stores. one of her cd's "Adagio" has 1,000 Words and real Emotion in it and she sings the version of 1,000 W. that yuna sang in the concert (Not the orchestrated version) but she added the extra lyrics that the orch. version had so its longer, and she addded some words to real emotion too.
