Damon, I've found a few of these on the forum, but they are all pretty low quality 192kbps MP3s... Am I correct in guessing that you actually have the analogue originals? If you can encode them as 320kbps mp3 files I'll happily provide you with a permanent server space on which to keep the demos, peel sessions and other unreleased material. You can then put up the links on the main page of your site.
Drop me a message mate.
James.
