The Ghost Of A Smile CD is well worth tracking the down. The remastering is excellent and they sound great!
I had five of the six Smile tracks (no "Doin' Alright" for some reason) on a bootleg CD I found in a shop in Greenwich Village, NYC, in 1995 and they sounded like they were copied straight from a Gettin' Smile LP, complete with clicks and snaps. Still, at the time, I was happy to have them in any form. That CD was called "The Unobtainable Royal Chronicle, Volume 1," and it had a bunch of other rare B-Sides and Extended Versions and such, so in the pre-internet days, when these tracks were nearly impossible to find without spending a crap load of money and going to conventions, that CD was a gold mine. I bought it and "Volume 2" at the same time and thought I'd found the Holy Grail!
For the record, "The Unobtainable Royal Chronicles" were both knockoffs of "The Ultimate Back Catalogue" CDs, but I didn't know that at the time and didn't care. I still have never come across either since, though I did stumble on "The Ultimate Back Catalogue, Volume 3" on CD in a shop in Toronto years later. I still have all three, though I've replaced all the tracks with mostly newer remasters or better quality transfers in the years since.
The In Nuce CD I listened to once at HMV when I saw it on the shelf and it sounded like the same transfer I had on the URC CD, though more muffled. Needles to say, I didn't bother getting it. The Ghost Of A Smile CD I found at the old Sam The Record Man on Yonge Street not long after and snatched it up immediately! Glad I did.
Anyway, back to Smile...
I love all six tracks. "April Lady" was always a favourite and of the three recordings of "Earth" that Tim Staffell made in his career, this one, I think, is the best. It's definitely my favourite. The other two recording were for Morgan's "Nova Solis" album (1972) and Staffell's "aMIGO" album, with Brian. Both feature Morgan Fisher, too. Fisher, by the way, played live with Queen on the Hot Space Tour and appears on the Live At The Bowl CD/DVD. Also on aMIGO is a version of "Doin' Alright" which is a complete re-imagining of the song and sounds way different from the Smile and Queen versions.
I like hearing the differences between the Smile version and Queen version of "Polar Bear." It's worth hunting a copy of that demo down. Still, though, my favourite recording of "Polar Bear" has to be Valensia's cover of it on his Queen Tribute album. That's one of the few times I think a Queen-related song reached its potential by another, non-Queen artist.
It's also neat hearing the earlier 1984 demos of "Step On Me," which sound pretty close to the finished Smile version. Find those if you can!
Lastly, good old "Blag". It's arguably the earliest version of the "Brighton Rock Solo," which happily lives on to this day. "Blag" itself it an alright song, but its real draw is the solo. Like "Brighton Rock" itself, I think "Blag" was mostly written to house the solo. Which is interesting when you think it lived there, then in "Son And Daughter," then "Brighton Rock," then freed itself live and began to consume other tracks, like "Bijou," "Last Horizon" and "Chinese Torture". It is the great unstoppable solo, rampaging through concerts like an awesome guitar rock Godzilla!
Long live Smile!
