Thanks for sharing this, Zombie.
If the source is Gout the different audio tracks available will not be hard to sync up. I also often read or hear people believing the mono mix to be the first original mix done and especially the remark of the Beru voice to be the original one when it was in fact the last made mix to the american release, I believe it was available to the public in June or July '77. A very polished audio track but I've never fallen in love with it. Unnecessary imo.
