Tim Jacques, I echo your nomination for "Dark Eyed Molly", although I am only familiar with the cover performed by Justina and Joyce. I really love this song! The song brings lots of vivid pictures to mind. I guess that, in addition to the haunting and rich vocals, is why I like that one so much.
Along those lines, I also love "The Banks of the Lee", by Silly Wizard. I can barely sing this one without crying. But then again, I'm a sap for those sad love songs where someone dies.
On the subject of rivers, I also really enjoy Alix Dobkin's "Over the Banks". (from that song)
And when the night turns dark as a dungeon
And not a star shines up above
I know I'll surely be guided
To the warm arms
Of my dearest love.
Rose
