John Book reports, with sadness, but also with video, that one of the founding members of Kraftwerk has left the band. My favourite reference to those German minimalists was at the end of the Flying Hellfish episode when the "rightful owner" of the paintings Bart and Grampa rescued. On his way out, the German said, in a thick accent, to the two Simpsons: "I must get back to Dancecentrum in Struttgart in time to see Kraftwerk."
