pye electrical - pye's of cambridge - got 50% out of the recording industry in 1955 when they sold 50% of pye records to atv.
pye electrical - pye's of cambridge - got 100% out of the recording industry in 1966 when they sold the other 50% of pye records to atv.
pye electrical - pye's of cambridge - were not, so far as anyone now knows or then knew, loath to the prospect of receiving any amount(s) of money that might be agreed between them and pye records' owners for an extension to their licence to continue to use the pye name, etc. in some any or all of the markets (or territories) of the world, upon their disc records, tapes, 8-track cartridges, cylinders, incised fine pottery wares, or any other recording media, post 1980.
the chaotic collapse of the atv empire (acc and various other acronyms & epithets more accurate by then) and loss of the rights to use the pye name & trademark was just part of the takeover battle(s) for it being waged by various australian millionaire entrepreneurs and the discovery that one of them had rather less money, rather fewer assets worth rather less than previously assumed, and consequently suddenly rather less creditworthiness - and very shortly thereafter, rather less credit - than had been the case thitherto: and an equally sudden embarrassing shortage of cash and cashflow, and an urgent need to sell off parts of the taken-over empire in order to attempt to keep control of the remnants.
I think the transition from PYE to PRT happened a few years earlier than 1980.
No need to speculate when we have a comprehensive Pye discography on 45cat. Showing the last releases as late as June and July 1980.
To mark the upcoming change of name, Billboard published a 36-page supplement on Pye/PRT in the issue of 3 May 1980. (This issue is not on Google Books.)
I think the transition from PYE to PRT happened a few years earlier than 1980. The circumstances were that after close to two decades, PYE Electrical wanted out of the recording industry so they pulled their trademark and the licence thereof from the record company who had used it since 1959. Not wanting to revert to using the "Nixa" name again, the record company rebranded itself as Precision Records & Tapes, or PRT for short.
Pye became PRT in 1980, so the date on this should be changed accordingly, with 1978 being the original on Pye International (I see that Discogs have it as just Pye, despite the International on the cover and labels).
deltics: quite probapossibly; but i've not seen the vinyl bearing the pye international - ?or plain pye? - label. (all sorts of things mayn't've happened as they oughter've had, in the unexpected-though-inevitable determination of the licence to use the "pye" name & logo - i completely missed the mis-step of the entire "precision" label at the time, ferrinstance...)
(pps: apropos naught in particular, my 7" tablettything's auto-mis-correct "feature" decided you were truly and properly "celtics" :-) )
"nspl" being the normal prefix for a full-price, main-label, stereo pye & pye international lp: i would imagine that this was originally scheduled to be released on pye international, having been allocated a pye international, n(s)pl 28nnn-range cat#.
