For anyone interested, this is my latest work on the intro to the Battle of Mustafar. This is a major improvement over my last effort to include Vader’s castle. To me, this gives clear context as to where exactly this scene is taking place (on Mustafar, near Vader’s fortress), because in the theatrical version, it is entirely unclear unless you have read the novelization.
The additional music is from the original piece that John Williams composed for the opening scene but was not used. I have already inserted this into my own edit of TROS.

Ack, I was hoping to take a look at it but it’s gone now.
