Next looking at Geffen/DGC singles, I've got the following alternate pressings:
Kool Thing 7" - UK version on the left, German on the right:
They both have the same catalogue number (GEF81/5439 19671-7), but the German version has a glossier sleeve, re-arranged credits and an extra line of copyright text. It's also pressed on much thinner vinyl.
I imagine that there's similarly alternate versions of the 12" too.
