I listened to that also. It sounds like La La has a pretty good relationship with WB (I even think it was said that they have the rights to some WB music) so hopefully they can get the soundtrack released.

Sounds like good new that the soundtrack will be on it’s way then.

Edit: I found a newly composed version of this theme on YouTube:
