Lots of help today, much thanks! Especially to John_Fred for providing his own research, and making me realize that my work ethic, as with Secret Crystal, is horrifically bad. V4 could not have been done without you in particular! And yes, I feel rather dumb for saying "the Ariston lead is dead, there's nothing to be found here", when I later get revealed that there were two tracks in there. Also a thanks for V2, though I doubt I'll be working on that any time soon.
Now, regards to nidostar, and his question regarding P.A. Ludlow. I believe this is a completely different person than the one on Discogs, ESPECIALLY given the fact that the P.A. Ludlow seen on Discogs was a) based in the Netherlands for the most part, and b) seemingly died out with disco. More than anything, I think that you MIGHT have a lead with Martin Kershaw or Alan Hawkshaw. Though Alan started off with KPM, in later years (with regards to LGFG1, and it's compilation in 1991), was with Martin Kershaw on Bruton Music. Unsure where the tracks might be, but a lead does exist in the Bruton library, then.
...then again, P.A. Ludlow was the original credit on all tracks of the album, so it could just be on the same line as The Martinez Singers, or, as previously mentioned, Johnny Peters. But, at risk of grasping at absolutely nothing, I'd say Bruton is a good place to subject for investigation - especially with Skyline and Awakening. Kershaw could also be a candidate on some tracks - I look at all the "Americana" tracks (Tenessee Twosome, New Mexico, and Brass Rass) especially.
TL;DR we have a new lead thanks to you, Nido! All help is appreciated!
Also will not forget about Lord Thames for mentioning Johnny Peters, one day that will be the target of de-Gibbs-ifying, I hope. Until then, that is much appreciated.
