In the 1980s, Turkey allegedly had a habit of modifying their songs drastically from the versions that won their national finals; "Halley" being no exception. What became the bridge in the final version was the original composition's chorus, with a more stuttery "ha-ha-ha-Halley" hook.
Klips ve Onlar consisted of a merger of two bands; Klips consisting of the band's (all-male) instrumentalists, and Onlar being the two vocalists (both female). Onlar member Seden Gürel is featured in this recording, however she did not go to the ESC final. Some (unverified) internet sources say it was because she had to sit her high school exams, others say her boyfriend didn't want her to go. She presumably left the band (going uncredited in their singular 1986 LP), and was replaced with now well-known singer Candan Erçetin.
I have attempted to remaster this version on Audacity from low-quality uploads that appear to be the only recording available of this particular version. I do not own any content in this video, all rights reserved © Türküola 1986/87.
