Just finished watching "Sgt Pepper's Lonely Hearts Club Band", the movie, on YouTube. Well, I skipped many, many parts, the whole thing is like a huge collection of music videos. Needless to say, I can see why it's rarely mentioned. It's an odd film, some of the covers are good but the rest really don't work for me; most interesting parts of this movie, for me, were George Burns (yes, even the "Fixing a Hole" cover), Earth Wind & Fire, and Billy Preston.

Speaking of Billy Preston, here's something that I noticed, as a Star Wars fan: when he's shooting lasers out of his hands, the sound is unmistakably that of a lightsaber being turned on:

and earlier in the film, towards the beginning, I've heard the sound of Luke's speeder a couple of times:

the same sound is used with the machinery in Mr Mustard's van, along with a couple of sounds from the Millennium Falcon

what in blue blazes??

The tie in here would most likely be RSO records (Robert Stigwood Organisation). The producers of the SPLHCB film, and also the distributor of the Soundtracks to Empire Strikes Back and Return of the Jedi, and the Re-issues of Star Wars and Story of Star Wars.
