Red 1 and 2 were originally on Bush, and then on Reload as well, the difference was that there were additional remixes on the Reload editions. Bush seemingly screwed Clarke over money on the Red series, part of the reason he never has a good word to say about Eric Powell.. although in fairness not a lot of people have good words to say about him!
Reds 1 and 2 were re-issued on Bush on red coloured vinyl recently..
