The world may never know, unless of course time travel is invented and someone shoves George through. Of course, he would probably re-release his movies each time a new musical instrument came out. "Battle in the Stars -- now with musical accompaniment on new Lucas Harpsichord!" Plus he'd splice in a lot of new footage and force theater patrons to come see it again.
Anyhow, I hope I don't sound bitter. Too much. I love the original Star Wars flicks, and this little silent film mashup that condenses all three of them into a little over a minute long is a fun diversion for a Monday. Give it a whirl and take a break from your day.
