Quick Update:
As things stand Disc 1 is complete (with the exception of a few small tweaks). Disc 2 has been a long effort do to a few problematic tracks. Disc 3 is about 70% done.
Among some of bonus content to be include is an excerpt from a 1986 Vangelis concert. The track is a medley of Memories Of Green and The Love Theme. Quality isn't great but I have cleaned it up (tape hiss/pop removal, speed corrected, etc).
