Krull The Conquerer was it?!
I miss the early 80s when sword and sorcery flicks were everywhere, D&D 1st Edition just came out, even Dio was affected (Check out the vid for Holy Diver) in the wake of Conan The Barbarian.
Anyway ... back on topic!
I disagree that different BKs can represent different 'types' of the JB's sound.
However, as I can't really prove otherwise, I'll leave it at that.
