Almost anything you hear on the soundtrack referring to Jabba the Hutt doesn’t exist in the movie. I do wonder if there’s a way to get all of that music back in the film - and there’s a lot of it - without it feeling cut-up and disrupted.
I think it would be a testament to Ady’s sound mixing abilities to restore some of it to the film. Luckily, sound effects shouldn’t be an issue.
While he’s likely using the ‘04 mixes as a base (with insertions from the OOT), maybe the ‘97 DTS would be a better starting point (if we have the DTS of it/if there’s a marked dynamic/separation difference between it and the ‘04/‘11).
