Satan Your Kingdom Must Come Down

This Great Depression-era blues/country gospel song was first recorded in 1931 by South Carolina evangelist Blind Joe Taggart. It was later revived in modern times on alternative country group Uncle Tupelo's acoustic record March 16-20 1992. Willie Nelson's take (included on his 2010 album Country Music) has guitar and vocal harmonies by Band of Joy guitarist and co-producer Buddy Miller.

Robert Plant's version was chosen as the theme music for the second series of the Kelsey Grammer-starring political drama, Boss. The song was selected following a discussion between the two friends. Explained Grammer: "We had drinks one night in New York and I had just seen his concert with the Band of Joy. He said, 'You know, Satan, Your Kingdom Must Come Down is a great song.' I said, 'Yeah, it is a great song.' I fought for it – I think it's remarkable as a piece to open the show. It leaves a mystery open."
