My girlfriend and I watched this on TV once, it was kind of okay (she loved it), I bought it for her, we've binge watched it ever since (I can't say no) and it kind of grew on me.
Eli Wallach and Jack Black's performances in particular are great. The former always makes me smile and the latter showed he has skills beyond goofing off (he went on to prove it at greater lengths, in my opinion).

Any way... The boys over at H-Z.com claim it's out there. Would anyone have it, per chance?

The list of composers that worked on this is kind of borderline ridiculous too:
Hans Zimmer, Lorne Balfe, Henry Jackman, Heitor Pereira, Atil Orvarsson, Imogen Heap, Ryeland Allison & Herb Alpert.

I can extract some of it from the 5.1 DVD audio (the music is pretty well centered, just a few sfx here and there so far I've listened), but the complete score would be preferable of course :)

I'm also very interested in this one! I just love this score!!!
So, I second this request. :) Many thanks in advance! ^^

Oh yes, I would like to see that one too! :-)
