A bunch of creepsters standing around being creepy.
It turns out that if you strip all of John Williams' classic score away from the original Star Wars film, you end up losing a good deal—if not all—of the emotional impact of the final scene in which Princess Leia gives medals of honor to Luke Skywalker and Han Solo but not Chewbacca for some reason:
See what I mean? What was originally a really triumphant moment kind of turns into just a bunch of people standing around, exchanging uncomfortable knowing glances with one another, cut intermittently with Chewbacca's annoyed yawps at the blatant space racism on display in the ceremony.
I wonder if that's why George Lucas decided to add music at the last second.
