I don't know who uploaded this but it's definitely me playing bass on "I'm so lazy" (taken from "wielingen walgt!", re-released on "I'm Sure we're gonna make it" and bootlegged on "Killed By Epitaph"
"Security Service" taken from "Als je Haar Maar Goed Zit (vol.)" released in 1981, the fastest 4/4/ drumbeat evahhh to my knowledge.
Another song from the same compilation.
