Leoj found a new source for the American Spanish ESB dub. Not as good-quality overall as the track from roback214, but good enough to patch over the bad areas he described earlier (with the help of the isolated score to help the music blend more seamlessly). FWIW, the missing scream is just how it was on this dub, so I just patched over the areas where the English audio was overlaid.

So we now have a patched-up ESB track (mostly the same as the original, just a few seconds altered) that sounds pretty much great. PM me if you're interested.
