I think this is actually "Egnatias 406" ("Εγνατίας 406 (Όπα-Όπα)") by Grigoris Bithikotsis (Γρηγόρης Μπιθικώτσης), but performed by Лаки Кесоглу, with official title "Бузуки" (from the same compilation as some other songs by him on your channel). Both versions sound quite similar, but you can tell the difference (at the very end, especially). You can find it on RUclips as "Бузуки" by Лаки Кесоглу.
