Yes, I know they have, but never knew there is a recording out there! I just checked and saw that I miss the releases after 1992. Not that many, and pretty much on the compilation side, but still with some songs I don't have. Many 7' singles as well. But I never had time to dig further with bootlegs and stuff. You can only have 1 (or maybe more) favourite artist(s) to look for such things, but unfortunately not all of them. No time and no money!
