Probably a long shot, this.

Lots of stuff used in the flick by Zimmer and Newton Howard - the end credits track rocked serious nutsack - was the extended score ever released to the world ala the recently rehosted Superman Returns score?

My friend, yep the same one, has heard the new Batman (2009) theme. I'll see him later and see if he knows anything.
Thought I had it, but was a bootleg 1989 Batman ost.

Batman89 bootleg? Upload & post puhleez! :D
