The song that closed the show on Sunday sounded like "let's go down, show me the way" or something like that. It was very beautiful and I'd love to get a copy on iTunes but I don't know the title or singer. Can anyone help? Thanks so much!

The title of that song is "Down to the River to Pray" and the version used in the premier was sung by Allison Krauss.
Yeah, it is such a gorgeous song. I got really excited when I heard it on In Plain Sight.

I don't think it's the same version, but the song used in the premiere was also used in "Oh Brother, Where Art Thou?" with George Clooney, as the song the sirens sang.
