I haven't even listened to the mixes, but the real version makes the disc a worthwhile purchase. I've never been a RS fan, but I have always liked this track and it sounds great on this release. I'm amazed at the quality of the recording for the age - this and Tommy prove that there were at least a few people around back in the 60s who knew how to record music. However, there is a downside - it makes other discs sound poor by comparison, Ziggy Stardust comes to mind as it is the most recent of my purchases.
