Here is a video of Tangerine Dream's appearance in the TV show "Bio's Bahnhof" on September 9, 1982. The title is "Das Mädchen auf der Treppe" which was used as soundtrack for the crime scene TV crime movie of the same name.. A short interview with Alfred Biolek in German language can be seen at the beginning of the performance. There are many videos here on Youtube from the same show in better picture quality than this one from me. But there the interview is missing. If you don't understand german you can't do anything with it. But in short summary you can say that Edgar Froese says that the music of TD can not be played completely live due to the complexity of the titles and compositions. It is preprogrammed from computers by calling up individual keys and buttons. The instrumentation used is very different from conventional musical instruments. This is only as information for people who want to know if Tangerine Dream is playing live, or what actually goes live and what does not. From this I can see that TD even admits that what many critics say, not everything you hear is played live.

But the played title is White Eagle...

Update 06.03.2022
Here I have tried to write down the short conversation or interview and translate it into English. AB means Alfred Biolek and EF is Edgar Froese.

EF: That's true, it did get a little too chilly for us in Germany. For the things we did...
AB: And you were abroad then?
EF: Yes we went via England, Australia to America and have now landed back in Germany.
AB: And can you be heard more often now?
EF: We are heard a little more often.
AB: Yes, I mean, you can be heard, for example, the other day at a "Tatort", The Girl on the Stairs.
EF: That is correct.
AB: That was a music that was actually a film score, but then hit tremendously.
EF: Yes, it has taken on a life of its own and, uh, it gives us a good reason.
AB: Yes, but can you also be heard live?
EF: Yes we will have some data in November in Germany.
AB: AH, Live, when you played yesterday at the rehearsal, a musician from Pepe Lienhard came up to me and said, is this really live it sounds like it's all from the tape because it's so perfect.
EF: Yes it's difficult, I mean all these instruments have a new technology which is already somewhat contrary to a normal set of instruments.
AB: You have programmed everything on computers?
EF: Yes Yes
AB: You not only play, you also call off?
EF: We also retrieve, certain structures are stored.
AB: They used to call, now they call off.
EF: Laughs
AB: Edgar would you still introduce us to your musicians?
EF: Yes here to my left, Christoph Franke on keyboards, synthesizer and Johannes Schmoelling.
AB: So, ladies and gentlemen, this music that is very beautiful, we wanted to visually embellish. We have asked the students of the costume design class of the University of Applied Sciences for Art and Design Cologne to present their costumes they have made recently to this music. The special thing about it is that all the costumes are made of paper. We now see this tablot together with the music of Tangerine Dream - Girl on the Stairs...
