Was the track “The Last Saber Duel” used at all during that battle? I assume it was meant for that scene? I think it would be interesting to take snippets from Duel of the Fates, Battle of the Heroes, and The Last Saber Duel. I think a combination of those tracks would be fun to hear.
I believe it was, yes. Not sure if in full, though definitely the majority of it was (it comes in during the final stage of the duel when Kylo walks through the crashing waves I think).
Personally I agree with Williams that it was right to cut the music during the duel. As it’s edited, it’s pretty short so it’d feel odd if it was accompanied with an epic, climactic cue like Duel of the Fates. But I’d still be curious to see how it played with that music.
