Sadly, I only have the digital versions of Star Wars. I saw the original without the add-ons during the nineties, but for the life of me can't remember anything but the explosion of the Death Star (and the cuteness of R2D2).
I had read somewhere about the Christmas special, but couldn't find it anywhere. Just a soundtrack on youtube ("Sleigh ride" with C3PO and R2D2 is... unique). Even though I'm forewarned about it's weirdness I'll no longer be in ignorance. :p Thanks, steph.
