I guess I’ll chime in, too. I think including the Imperial March fits in well with this project’s intentions. It’s not meant to replace the original, but be an uncompromising Special Edition with good taste. Ideally, though, there wouldn’t be an ESB-thunder-stealing montage of an Imperial fleet when we first see the Death Star.
Not that any of it matters, as it’s Adywan’s call and he was clearly happy to include both in the original Revisited.
