Theme from the trailer...

I'm pretty sure I've heard about every song on the soundtrack (thanks to Blue Laguna) but I still can't find the theme from the Rogue Galaxy trailer that begins with the line, "Jaster has dreams of exploring the galaxy..."

I hope that it isn't indeed just some random cut of music leftover from the game development that they decided to simply not do anything with and left it off the soundtrack. I'd really like to know what it is.
