Tödliche Doris: "Über Mutti" (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.
