A lot of artists have recorded this song. It was The Greek Eurovision Song contest entry by Antique. (I think the translation means "I would die for you"

Also it has been recorded by:-

Yannis Ploutarhos
George Missikos
Vicky Leandros
Ferdi Ozbegen
Giannis Ploutarhos
Valadis.

I don't know who recorded it first.

Demis roussos has a lovely voice. I remember his music from the '70s.
