I'm glad you finally got it Andy- sounds like it was worth the wait for you.
The Paramount disc is my favorite thing in the box, and probably one of my favorite things he's done, ever. It is truly amazing how that band can still bring it.
I agree, there are some gems on the vault footage as well- I absolutely love "Something in the Night" from Red Bank '76. I'd also love to have heard the rest of the early version of "Candy's Room" (House at the end of the street?) that Bruce was playing on the piano in that small clip- it sounded even darker than the finished guitar version.
Phoenix '78 is great- the pity is that the whole show wasn't filmed (that we know of), thus those few songs are all there is.

I think you'll like Houston, though.
The outtakes set does have some excellent songs, although "Spanish Eyes" isn't one pf my favorites. On the other hand, I think "Ain't Good Enough for You" could have been a huge hit, regardless if Bruce or someone else recorded it. I'm kind of glad he saved it, though, so we get his version first.

(Shame we had to wait 32 years) Rendezvous is cool, but not too much different (aside from a few lyrics) from the "Tracks" version (which was live).
I think the album remaster was done pretty well, but after hearing Paramount, for me it's a bit of an afterthought. I don't think I'll play the original album much, if at all, anymore.
I'm curious about your guesses as to which vocals are new/ old? I think I've got most of them, but a couple have me scratching my head a bit- "Rendezvous" is one.
