klepsie: so they both were, whilst pete chester and the consulates were not; i dunno, though the reason given for labi siffre's records being released by them on pye international was that, despite his being a british artist, his recordings were produced by an outside company - festival records international - in merkia, in a new york studio. (which i'm not at all sure was true of all of those pye records released - but maybe by the time one wasn't, the "principle" of him being a pye international artist (with one slip-up, air) had been established.)
The Pye International consideration has been noted on other records, without explanation. I assume it was because they leased the tracks out , rather than a contract for services with royalties? If later I guess would have been on Piccadilly which was formed in part for such situations within Pye.
