This contains everything you could possibly want to know about the set, and which tracks are NOT DUPLICATIONS of tracks that are on his other albums. Don't trust the liner notes of the set itself- there are inaccuracies. Trust Chris innstead!
Unfortunately, 2/3 of the set is a bunch of rehashes of things that most Neil fans have bought already. But, with the new, lower price, it brings the price-per-useful-song ratio to something a bit more realistic.
