Ok so that is your take and people interpret things differently. It does not mean you are wrong but for me to describe this "theme" I will do so specifically.
It is heavily inspired or influenced by a funeral march in it's rhythm and it's somber tones. It is often misquoted as being "Bobba Fetts" theme but it is not about him. It is about Han in carbonite although neither dead or alive being carted off in a floating coffin by his storm trooper undertakers. The music communicates this very clearly in the way it is fashioned.
So I just want to be clear that there is no silver platter although a valuable resource you still need to use association specifically when you get either a strong change in either rhythm or a specific theme. I am just trying to be helpful to you because I think you are a good bloke :)
I now understand what you are saying about Brian Risner Remix and how certain recordings are altered. And the Eric Tomlinson Film mixes shed a much greater light on the actual score sessions and are accurate to the actual film score.
