A. 1983.

Yub Nub is the cheerful ending of a film in which the good guys have won and the central characters are all alive and well. The 1997 music is an alteration to fit the revisionist take that the films are all about the Tragedy of Darth Vader, with a the sadder music being a nod the to bittersweet ending of that tragedy. The films are all about Vader suddenly, so it's not such a happy ending, because he's dead, so the music has to mourn him. I'm all on board with Vader's redemption and death, but the story isn't about him, it's about Luke and Leia and Han. Vader's just the villain who got redeemed. He got mourned in his pyre scene. He doesn't need to get morned in the ending music too. The 97 music is warping of the film and a misrepresentation of what it was about. Yes yub nub is childish and silly, but I accept that because I accept ROTJ as what it is. Glowing happily ever after ending is the order of the day, not "Here's the end of the tragedy of Darth Vader." Star Wars is a fairytale, not a grand tragedy. I'm not going to accept Lucas pretending it's something it's not.
