This definitive edition is unfortunately not complete, I have the disc too... There's one sequence, something like a ''future flashback'' (yes, there is a track named like that, but I'm not referring to that one). It has some of the tense pieces from the Main Titles, but is like an extended version of that.
The exact scene is when he sleeps in a car and dreams about a future battle. It's on YouTube: YouTube - Terminator Future War (

Does anyone have it? Or does anyone have a complete score for T1?
