The two songs that pop into my head right off the bat (get it? bat!?) are the Sting song off of Dream of the Blue Turtles called.....Moon Over Bourbon Street, I believe, and a song on a cd I just bought by Gino Vanelli. It was a 1995 release, and I'm buggered if I can remember the name of the cd now, but the song is called Moon Over Madness (hmmm, sounds like a running theme, here...). They are both very smokey and jazzy, and capture the haunting atmosphere I suspect you are after.

I can't think of any Folkey pieces yet, ut I will put it in the old processor and see what bubbles up.
