A1 mixed by Cabaret Voltaire and Parrot
B1 and B2 mixed by Derrick May
Produced by Cabaret Voltaire, Robert Gordon & Mark Brydon
The Sweet Exorcist Mix is not by RHK & Parrott. It's was a Cabs mix that should have been titled "Universe Works Mix" but EMI's marketing department changed its title without the Cabs' or Parrot's consent. The Mayday & Sleazy Dog mixes are genuinely Derrick May's work.
Also, there is new evidence of a CD-single (promo, perhaps?), and I am awaiting further details.
