I've bought everything I could lay my hands on brand new and stuff i've come across at record fairs. The rest like rare remixes I've filled in on mp3. I wouldnt expect much sympathy on this forum if all my Underworld songs were in mp3 though.
And Kistrael, dont worry about 34958hq439-qjw9v5jq298v5j/TypeCross/DerKommissar. He's got this Freur/Underworld mk1 thing going on
I'd concentrate on the Underworld Mk2 and Mk3 stuff if I was you.
