I have a tape of this, don't know what year it was recorded (I think ITV showed Star Wars several times in the eighties) but I thought it was around 1982. It does not include adverts, and the beginning and end are missing.

The value of this tape is in the soundtrack, which is the rare mono mix. I captured it and synced it up to my laserdisc transfer. See:

Personally I don't see the attraction in VHS-quality pan and scan when you can have laserdisc quality widescreen, so I didn't capture the video. (Perhaps I'm not as "nostalgic" as you lot!) I do know however that Russ made a DVD out of one of these ITV recordings with his DVD recorder.

bigrob, if you could find your tape, I know someone who'd be very interested to know how the audio compares with mine (specifically: dynamic range, signal/noise ratio and how much, if any, is missing).
