Ah yes, that a capella version is really good. Very clever piece of work. Another band which gets a gernsey on the Virus 100 album is Alice Donut. Their song Lisa's Father (youtube clip, well worth it, creepy child abuse triggers) derived from a seriously fucked up Jack Chick comic a great piece of work.

MDC kept changing their name according to the single they were bringing out - Millions of Dead Children and Multi Death Corporation are two names I remember. I have the single of the former on vinyl...
