This has been bugging me for ages. I got this tape that was circulating just before the release of Impurity which has all the finished mixes and b-sides plus a A Far Better thing and the acoustic version of Luhrstaap on it. I think it was called the 'Impurity Studio Tape or something like that and I remember feeling very important and 'in the know' back then. Anyway, the interesting thing is that the version of Space has a male voice doing Joolz's spoken word part. Otherwise it's identical to the Impurity version.
Does anyone know more about this? I'd be happy to share it but I have no idea how to get a cassette into the internet, if you know what I mean.
