The Alan Silvestri score in Alderaan destruction, in my opinion, I think it would make everyone feel dreaded instead of sad.
If Alderaan’s destruction comes immediately before Luke in the homestead cleaning the droids, Obi-Wan would’ve sensed the destruction offscreen. Alan’s score for destruction of Alderaan, Luke seeing Leia’s hologram for the first time, Lars dinner, and the binary sunset with ROTS Score ending the first act and vegins the credits would’ve end on a hopeful note.
