zounds' entire discography is available on a cd, curse of zounds, issued in the late '90s by rugger bugger over there & broken rekids over here. ditto for the mob's let the tribe increase.
similarly, all of dirt's first-incarnation stuff (they re-formed a few years ago & have done at least a couple of 7"s & maybe a live album) is on a 2cd called black & white.
