After typing in these lyrics myself, I found a page which has lots more information about the Subhumans than I will, in all likelihood, acquire. If you're interested in the band, I'd strongly urge you to go to this page.
Their entire discography (with the exception of one song it seems) is available on 6 compact discs. The discs are relatively inexpensive (around $10) and you should be able to special order them at your local music store. If not, there's always cdnow.com, which I've ordered from a few times (one order was, in fact, to get the last of my subhumans albums on CD) or Secret Sounds, my music store of choice.
