This one is considered a classic. Nana Mouskouri, who recently retired (I believe she is in her 60s) is the biggest selling female artist worldwide ever, with fans all over the world, even though she is not well known in the US.
While the melody is Song For A Winter's Night, the translation does not attempt to match the original lyrics (the French title means "at the garden gate". Nana also recorded the song in English (she was fluent in at least a half dozen languages; her native tongue is Greek), and recorded a French version of Sundown. Although her name may be new to most of us, she is mentioned in the official Lightfoot bio.
