And again for 100%...
UK 7" [DGCS 11] on the left, German 7" [GES19077] on the right:
(The scans in the discog are of the German pressing, though only the UK version is mentioned in the text)
Same story again with the 12":
This time the UK version [DGCT 11] is shoddier - they're both on similar quality vinyl, but the UK pressing comes in a flimsy top-opening slip-in sleeve, while the German version [GET21735] is housed in a "proper" sleeve with an inner.
I believe there's also at least 3 pressings of the Dirty Boots 12" [US/UK/German] but I don't have the evidence on hand for those.
There may well be further European variations too - there's French, Spanish, Dutch & Scandanavian pressings of Nirvana singles from the era, so Geffen could well have done the same with SY to some degree...
