msycamore said (about "Carbon Freeze" and the SE missing bit) :

Its placement on the SE is correct, you can even see when he conducted this part to the scene on the BBC documentary "STAR WARS - Music by John Williams". (a very good one, recommend it if you have not seen it)

... And said:

ABC, when I told you that the "Carbon Freeze" cue's placement on the SE CD is correct, it's both right and wrong.

The music was written for the scene, yes. But was dropped, so it's still an Alternate for the music that follows. So on the SE CD you have two parts of music describing the same scene after each other, it's nothing wrong to have it that way, but I would prefer to have one of them on an alternate version.

Just a thought, sorry for not describing it better.

I come back on that as I'm currently watching the BBC documentary. Not only the missing bit is well placed, but it is part of the "Carbon Freeze" track, as I feel when listening how they fit. My real grip with that missing bit is that it doesn't fit with the beginning of "Darth Vader's Trap" (what doesn't matter anymore as they are separated).

This missing bit then is going be given back to "Carbon Freeze" on Version 4.
