I grew up in the sixties and early seventies with ar' kid's cast off (UK) vinyl, Motown, London, Mojo, Immediate etc and although I loved 'em at the time, when I first discovered the overseas big holed, multi-colored (sic) beauties, I was sold.
Of course I appreciate the look, durability and response of UK released soul, you can't ignore it, but after discovering the dodgy design, flamboyancy and colour of US labels the rather stiff looking UK labels never really did it for me.
I think a lot of my tempered love of UK vinyl is in my head due my earliest memories of UK vinyl.
Of it being scattered in sleeveless piles on the floor of our lobby, mixed in with dusty 78's, or forced 6 a time onto the spindle of our Dansette (that awful spinny-scratchy sound as you loaded/spun 'em on always stuck in my head), before it clattered onto the turntable and the 'needle' began it's panel pin progress.
As objects they seemed unloved in my memories, utilitarian at best - but that was a sixties child at work I guess.
Flip to my light fingered, two sleeved treatment of my first US acquisitions and coupled with the thought that the UK releases of US tracks had never been anywhere near their producers and it'll always be the US release for me.
