Music To Write To: I Shall Not Be Moved
Most of us know this song as a civil rights anthem, in the form of "We Shall Not Be Moved." It began its life as an African-American spiritual, with its roots in slavery, but was first published as a hymn late in the 19th century, and has been sung both as a hymn and a song of protest ever since.
I like Johnny Cash's version, for the purity of the lyrics, and Mississippi John Hurt's, for the beauty of the arrangement. For anyone who wants to recall the Movement, there is also a 1964 cover by The Seekers.
