I am looking at it with a bit of an open mind because it would appear that the actual scene where Han is Loaded on to Slave 1 has a missing scene... This explains in the Gout the music for the Slave 1 scene being screwed up and cut short

It was meant to Have Fett climbing a ladder and saying "Seal it"

Also the whole Slave 1 sequence was meant to take place Just before the heroes ran through the door to try and save him from being carted off so it was moved because of script revision.

The special edition sorts the music problem out but also (This is the part I am not sure about...) Perhaps slows down the score so it joins the light saber duel and was perhaps never originally intended to?.

It was.
