(I will now imagine that I can faintly hear the ambient sounds of breathless, curious hippies in the background of that millennium falcon shot)

The nice thing about that interview is that it had a few "demonstrations" of Ben making sounds from mundane objects. E.g. a slinky making "pew pew" sounds. Or objects making sounds for some of the old Disney cartoons. It's quite amazing what they were able to accomplish with relatively small constructions/gadgets.
The new trilogy never quite "felt" right, there was always this disconnect of the visuals and the sound effects. I remember seeing a video going over how they built up the sound effects for the pod racer scene and, while it was interesting, I never really felt like the sounds fit the film in the same way the sounds did with the original films.
Here's an example from Pink Floyd's Dark Side of the Moon
Strange how the brain works sometimes.
