Yeah, but in order to do a worthwhile reconstruction, you'll need all the alternate takes (Lando's lines for example) in good quality, are they even available on other sources? and altered footage to support it. But it shouldn't be impossible with all the technical skills around these parts, I guess.
I can't thank you enough, morgands1 for sharing this, such an amazing treasure. Never thought a recording like this would surface after all these years. :) Also nice to hear all the responses in the audience.
