Well, I checked it out. I thought "50th anniversary" meant some sort of retrospective/reissue overview of albums from his career. Turns out it is just that one self-titled 1971 recording. What was 1 CD is now 4 (+ a live show DVD) filled out by 30 outtakes and alternate takes. Just $105.99 on Amazon (slimmed down offerings also available, I should point out). But 30 outtakes and alternates? I'm thinking there's probably a reason they were left off the original release. No offense to fans or his estate but for me, personally, I find this kind of stuff annoying.
