Thank you for the reference. I like the Internet Archive very much, but I didn't know they had songbooks. It looks very interesting, if only I could read French.

I suppose it's worth mentioning that my lead sheet differs in that I wrote in the harmonies as chord symbols. Of course, they're the harmonies of the accompaniment, which aren't authentic. On the other hand, they are, from my point of view, better than nothing, unless you like unaccompanied singing. This isn't my favorite kind of performance, but that's just my preference.

Anyway, the harmonies aren't written in stone and can be used as a starting point. I think they're quite good for this song and not fussy or overly fancy and sound Greek to me, although I am admittedly no expert.
