only differs in your mind
The Imperial March, aka Darth Vader's Theme, made its debut in 1980 with The Empire Strikes Back, standing as master over all he surveyed on the bridge of his Super Star Destroyer the Executor, not 1977's A New Hope. Although I'm rather surprised a small musical clip of that theme was not added to his entrance on the Tantive IV with the special editions. I guess the original was good enough, it works for me...
