This was written by Chris Isaak's bass guitarist Roly Salley, and was originally the title track of Salley's 2005 solo album.
This song was used in an advertising campaign for the chain store JC Penney, which features sentimental images of "heartland" Americana, such as family reunions and Fourth of July celebrations.
Robert Plant recalled to the London Times May 3, 2008: "When I first heard that song, after T. Bone (producer T-Bone Burnett) sent his collection of songs, I was driving through the Welsh borders in Herefordshire. I just stopped the car. It was so poignant, so masterly."
Krauss added in the same interview: "And the melody was so. When you combine a melody that lifts you up with a lyric like that, it's a twisted thing. When you get that combination, that is really something."
This was #51 on Rolling Stone's list of the 100 Best Songs of 2007.
