In Bulgaria many years ago, when we had only two TV channels, there was most popular broadcast for decades and was recognized as the most successful in the history of Bulgarian TV. It remains unclear who is the musical composition, used as background music of heading "interlocutor optional". In early 90-ies of the 20 th century in some metropolitan cinema was screening pornographic film in which during one of the hardporno scenes sound the same composition - it gives great surprise reactions among viewers (according to recollections of eyewitnesses posted around the forums) and actualize the topic of that, how for a decade no one reported whos music is used in the most prestigious Bulgarian television broadcast of the totalitarian era. Among the mass false versions of the music is "Vangelis", "Lotto," "Zodiac", "Herbie Hancock" and many others. We know that for some of the headings used music of Jean-Michel. But here is sample of background, that no one know who is it at the present time! Please, somebody to HELP US!
1978 / 1979 Heeeeelp!!! Pleeeeeeease!!!!!

But it's impossible, because kraftwerk perform slow down electro and his music allways seem phlegmatically. We must try to recognize the song. If we find the name of song, we learn who is artist!
