In 1984, Bohlen cited the hit single "Precious Little Diamond" (by Fox the Fox), as his inspiration for using falsetto choruses. The studio vocal line up of Rolf Köhler, Michael Scholz, Detlef Wiedeke and (on early albums) Birger Corleis, in addition to Bohlen and Anders, produced the high choruses characteristic of Modern Talking. Köhler, Scholz and Wiedeke later went on to work with Bohlen in Blue System, before joining with songwriter Thomas Widrat to form Systems in Blue. Köhler, Scholz and Wiedeke were never credited on the Modern Talking albums, and eventually went to court over the matter. They received an out of court settlement and Bohlen published a sleeve note for his next release ("Obsession", by Blue System), acknowledging the trio's contribution.
