I came across a blog post a long time ago saying that while the FYC promo for The Wrestler (which was further trimmed down to be the iTunes single) was complete in terms of music that made it into the final cut, Mansell wrote an additional 20 or so minutes that were unused. Does anybody know if this is true, much less available?

The FYC promo is 12 cues, 12 minutes which sounds about right from what I remember hearing in the film. There's a 60 minute version floating around that has 34 cues. There's maybe 16 cues and around 25 minutes of unique score on it. The rest is different mixes.

You wouldn't happen to have access to that 60-minute version, would you?

I'm interested as well.
