IMHO, some tracks are original sessions while others have been editorially changed somewhat crudely to match the flow in the episodes. The set seems inconsistent in that regard; sometimes "clean" and sometimes "edited" -- the original tapes were, according to the producers ~ 150 reel to reel with ~ 30 minutes each - that means ~ 75 hours of material edited down to what we have on the collection. "IF" you can condense the material to that size and be complete, then I see no problem at all. Certainly there are going to be duplicates of music; however, if you CHANGE the way the music is recorded OR edited, it becomes a unique work
that neither matches the episodes nor the exact studio recordings... which I think is what we have here. It is fine for casual listening, but not an enthusiast item. That is my opinion, of course.
