Yep, although it appears that they still haven't re-added the 30 additional minutes from Peckinpah's original cut. That film may not exist any more.
Not that it would fix the problems on the movie. If I remember correctly from Weddle and Seydor's books, Peckinpah ran out of money and time before filming most of the scenes showing Dundee's decline after being shot. And he never filmed the massacre that was supposed to open the movie. Seydor lays out some of the discrepancies between the script and the film in his book.
Anyway, I understand that the re-release has an alternate score and 15 minutes cut from producer's first take (which came after the 30 minutes cut from Peckinpah's version). I think having new music would be key. The less Mitch Miller, the better.
Also, flawed movie though it is, I'd walk over hot coals to see it on the big screen if it was feasible. Here's my crappy take on the movie for the High Hat (reading it again makes me wish I'd put it through at least one or two more drafts and wish further that the Hat had a copy editor in those days): [link]
