What child is this is a Christmas Song.

The beginning words go like this.


'What child is this who lay to rest on Mary's lap is sleeping. Whom angels greet with anthems sweet. While shephards watch are keeping.'

They play this tune in the game or a tune very similar to it. In any case. It sounds like they copied it from What child is this. It is played in the beginning of the game when Tidus is looking around for the things in order to light the fire.
