So, I'd say that sounds pretty good. Now I could be wrong about some of the Previously Unreleased tracks. But what I mean is that they WERE Previously Unreleased when this set was made back in 1975. See, I think the thing is, the show was very young back then, and they did not have 60 songs done by celebrities, which is why they couldn't have done it.
