Which versions did you use, if you can remember?
And wow, I actually didn’t notice that TFA and TLJ seem to use the same recording for the Main Title. If that’s the case, Episode IX will more than likely use the same recording as well, and I personally think it would be interesting if each film used a unique recording.
Since IX will probably be John Williams’ last Star Wars film, maybe he will re-record it. If he doesn’t though, there are some more options.
I did manage to find a few more versions of the Main Title, such as this one:
Varujan Kojian, Utah Symphony Orchestra, 1983
But after enough searching I actually think I found enough versions actually conducted by Williams that could be used for two prequels and two sequels.
John Williams, Boston Pops Orchestra, 1993
The Hollywood Sound album, 1997
John Williams and the London Symphony Orchestra
John Williams Conducts John Williams, 1990, Skywalker Symphony Orchestra
I didn’t know about this, but John Williams actually came out with a collab album with the LSO this year of some of his greatest hits!
John Williams, A Life in Music, 2018
London Symphony Orchestra
So I definitely would have to go with these four John Williams recordings, that way they are all still Williams:
Boston Pops Orchestra
The Hollywood Sound, LSO
Skywalker Symphony Orchestra
A Life in Music, LSO
These can all be found on Spotify, but I believe all of the albums are also available on Amazon, and you probably can find YouTube videos of them as well.
Unless others can find more options, these would be my picks, though like I said, not sure which recordings could go with which movie. They all have a unique sound, and I just thought it would be a cool idea to showcase some of John Williams’ other great performances of this classic theme that people might not usually hear.
