Deadly Doris: "Super Mom"(1984)

German music and art collective Die Tödliche Doris performs their song "Über Mutti" live at the Front Kino in Kreuzberg, Berlin in 1984. However, the performance is actually a lip-sync of a live recording of the song at a concert in Paris a year earlier. The audience themselves are invited to join in the performance, syncing their responses to the recording of the Paris audience.
