John,
Surely Otis Clay's "The Only Way Is Up" LP was released, promoted and marketed in the early 80's in the US & Japan as a new, contemporary release even though certain tracks had previously been released on other labels several years earlier ... while the Sandra Wright LP was very obviously a compilation originating in the UK on Demon Records of previously released and newly discovered material , and it was clearly marketed as such , wasn't it ?
Not that any of that matters as far as the musical quality is concerned ... they are both great LPs of course !!!
In fact, and I've said it before on here several times, the only way to play out Otis Clay's "The Only Way Is Up" is off the said original LP because the sound quality is so unbelievably good, loud and clear, and it doesn't have the nasty hiss and jump at the start which most the 45's seem to have. And YES... it is absolutely OK to play the original LP ahead of the original 45 ... even at an OVO event !!!
