Radical Grace/the Lutheran Difference

The opening theme for Radical Grace Radio, in it's entirety.  No, this isn't necessarily what Sunday morning worship music should sound like.  I remember getting the idea to do an upbeat version of this old Advent Hymn when I heard the Choir at Concordia Seminary in St. Louis do it as though it were a march...  The impression I got was it's a song you sing as you're carrying the Good News to "Those who sit in Darkness".  We all decided this should be the theme for the show, since most other shows already use "A mighty Fortress" as their opening theme.  Speaking of "A Mighty Fortress", listen carefully in the second verse for a re-iteration of this famous melody.
