When I was a wee boy - all of the Death Star scenes, hiding in the cargo hold, sneaking around in disguise, storming the detention centre, the trash compactor, getting chased around, the chasm, the tractor beam, the duel, the escape and the dogfight - that was Star Wars to me. You could lop off everything prior to the arrival at Alderaan and everything after "Help. I think I'm melting!" and it would still be miles better than a lot of movies made before and since. In fact I think that some 8mm versions of the movie do more or less that.
