I made a small research in the Internet.  The title of the song is "kokkino skotadi" which means "red darkness" and the singer is Parios. Unfortunately I didn't find a video with this singer who is one of the best singers in Greece. Nonetheless, I found the same song sung by another singer who is not as good as Parios but it was the only one available. The singer is called Makis Zappidis. You can find it on you tube as " κόκκινο σκοτάδι Μάκης Ζαππίδης live".
