lol I remember them, but I never bought anything. I remember the news-story breaking that they weren't really singing on their records, they were just a facade for Frank Farian and his band of session musicians. That revelation didn't surprise me because Frank had worked like that for years. What did surprise me is they chose to press their own self-distruct button by 'coming out' instead of just rolling with it.
I also remember Rob Pilatus' death in 1998, ironically enough on the eve of a promotional tour for a new album produced by Farian, but this time with Pilatus and Fab Morvan genuinely on vocals. Shame. I can't remember if the album was ever posthumously released.
