Spunky Onions meets The Ghettoberries

This was either a "split" single (or maybe EP, perhaps?) out of Britain around 1979 or so...it was the same band but under a different guise on the flip side. I don't know if they released anything else or not, but all I've heard is the funky chugging "Spunky Xpress" and the gentle punky-dubwise pop of the almost Scritti Politti-esque (to the point that it would make an excellent companion on a single with "Confidence", not to mention that I'm almost convinced Green Gartside made this single) "How I Lost My Virginity", both on the Spunky Onions side. Has anyone else heard of this lot or heard this single or knows anything about it? "How I Lost My Virginity" did appear on a Messthetics compilation, if that helps...
