Did you ever see this entire film? The Birthday Party recording in Hansa Studios in Berlin during '83. This is clip here is definitely the best part of the entire 25 minute film. They should have let this dude just make an entire instrumental album himself. The entire film is cool to see, even if you are just interested in seeing Hansa Studio circa '83, the equipment, and the recording process:
