GoodMusician,
First off, in case you're unaware, the link to your files is currently down. I only just discovered them a few days ago, and in the middle of downloading them my old monitor burnt out on me- and since I've gotten a new one the link has been down & I've been unable to finish. However, what I've heard so far is spectacular and I eagerly await the rest.
More to the point, you are obviously very knowledgable and I've enjoyed reading your posts about the soundtracks. Since you'd be the one to ask (and unlike folks at Lucasfilm, likely to answer) I have questions about some of my favorite music, Lapti Nek and the other 2 Max Rebo source cues.
1. Many, many years ago, my research on the internet (for what that's worth) indicated that the masters for this source music was somehow "lost in the archives." Somewhere back in your posts (it may have been in your letters sent to Sony about the 30th Anniv. CDs), you mentioned that some lost masters for ROTJ had been found. Through your contacts, do you know if any of these three tracks (Lapti Nek film version, Max Rebo #1, & #2) were actually found or are they still in the 5th dimension somewhere?
2. This ties into my ignorance about the technicalities of film soundtracks, but whenever I discuss this issue with anyone, the subject always comes up, something to the effect like "Couldn't they isolate that element of the score off of the soundtrack?" Now obviously it wouldn't be complete and quality like a master recording, but say IF George or whomever wanted to (much like you did to make your versions of the tracks in question), could they pull the music only out of the mix (however that's stored) and get a fairly good result? This is especially true of Max Rebo #1 & #2, which would be part of the more recent SE mix. I'd doubt it ever happen, but I'm just curious from a technical standpoint how good you think that could be.
3. Somewhere else in your posts you mentioned something about Joseph Williams having written a source cue. I'm familiar with him having written the English lyrics to Lapti Nek if I'm not mistaken (which can be partly heard on the "SW to Jedi" documentary), but didn't think he wrote any music. Is this something different and what do you know about it?
Thanks & keep up the excellent work!
