[snip] I'd imagine that Lucasfilm's warehouse is probably pretty well organized since Lucas held on to everything for those 20 years between the theatrical release of Star Wars and the Special Editions, and it hasn't even been that long since then so I'd be surprised if any has been lost, especially since the "Empire of Dreams" documentary crew supposedly had access to the Holiday Special tape, and I'm sure if Lucas wanted to destroy anything, it would've been that.

I have been meaning to revisit 'Empire of Dreams'; I don't think I've watched it again in ten years - since back when the first Trilogy DVD set came out.
