KICA-1389~90: WILD ARMS Complete Tracks

[Rimo]

I've recently stumbled upon a piece of information, which is that the end credits theme in the American version of Wild Arms differs from the Japanese one. Plus, it seems this different theme is not included on the soundtrack release.

A video of the credits sequence can be seen here.

Since I've never really played to Wild Arms and haven't listened to the whole soundtrack, I was wondering if said credits theme is an original composition or an arrangement of various game themes (my guess would be the latter since it's a medley)? What bugs me is that it's credited as is:

Music Finale

Composer:
Chuck Doud

Producer:
Buzz Burrowes

"Composer" being the ambiguous word.

I would greatly appreciate if anyone could share some light on this. The info will be used to update Chuck Doud's profile on VGM Rush.
