Sorry I'm late - been away - but I have nothing to add anyway. The song rings no bells with me, from the lyrics posted here; perhaps if I could have heard the tune it might have helped.

Newell translated a number of Hadjidakis' songs, most notaby The White Rose Of Athens, so it would make sense that this could be another of his translations. But those translations did not always match the original lyrics in storyline/theme, which explains why the lyrics above ring no bell with me... Sorry!
