I don’t think the audio is lost it is a case of them not allowed to share it for some reason perhaps music rights issues or something.

It would be good to see this vetsion however the ending looks pretty bad on scottish picnic party. I would probably go with everything else though in the cut. The deleted ending of Highlander 2 has the deleted Sean Connery voice over for the ending of the original film though. So I think some of that footage with the deleted connery monologue or even scottish highlands footage then cut back to theatrical version would be the way to go on the ending.

The real good scene is Connor and Rachel apparently whilst the extended fight seems good to me also.
