I'm total agreement with you...however....Since it's Lucasfilm, you'd have get a license directly from them to release it. The reuse fees shouldn't be the major issue here unless this is going back to 1992...I think something could be worked out, but the main issue would be dealing with Lucasfilm on a license for it and I honestly don't know at this point if they're willing to do it. I hope they are up to it because i would love to see the complete score to Indiana Jones and the Phantom Train of Doom by Joel McNeely to me one of the best scores of the series and basically influenced by John Williams.
I'm all for reissuing or expanding the music from The Young Indiana Jones Adventues series.
