I guess I'll respectfully disagree as Naked was released by them and which was, I believe, a group effort (although I'm not sure what you mean by group effort). Naked just represents Let it Be as apparently they wanted it to be when they recorded it: true to the get back concept, not over produced.
Brad, what I mean is "Naked" is not something released by the group when they were a group. Which puts it in there with Anthology, etc. which also are not part of this reissue program.
