This video is beyond explanation. The title loosely translates as, "I'm very happy you see, finally I'm returning home."
I thought this was the title of the song. Perhaps it is. This gentleman was not informed though. Unless this is just some sort of interpretive piece. I have a theory that he is gesturing at an "Iron Curtain" with love. Also that he may be under the influence of some of that psychic science they were working on over there.
Why bother talking about this. Watch the video. Your life will instantly improve.
