I can't find it on Youtube, but I did find what appears to be some fascinating behind the scenes footage from the shoot!

Interesting that bits of the Death Star docking bay control room set were still around when this was shot. (Circa 1979?)

Chunks were repainted and put into the Executor set in ESB (possibly including the bit that is replaced by the televison behind a plastic dome thing here) so it makes sense that other bits would still be tucked away in Elstree as late as then (they might have hoped to recycle them too).
