[Kraftwerk] "Der Android"

The WDR radio play "Der Android" by David Gieselmann and Christoph Kalkowski from 2001 gives credit to Florian Schneider and Ralf Huetter for the music and to "Studio elektro-automatisch / Klingklang" for production. Unsurprisingly, the music is simply a compilation from old Kraftwerk albums, but does anyone know if the radio play was *really* co-produced at Klingklang? Thanks, Klaus Zaepke
