First, some background from Wikipedia:
Silicon Teens were a British virtual electronic new wave pop group. The project was the creation of Mute Records founder Daniel Miller, with Frank Tovey acting as the band's fictional frontman.
The "group" were publicised as a quartet with members named Darryl, Jacki, Paul and Diane, but in reality these individuals did not exist and for media interviews their parts were played by actors, with the band's lead singer Darryl portrayed by musician Frank Tovey. Tovey did not perform on any Silicon Teens recordings; All vocals were actually provided by Daniel Miller.
