You've probably heard the argument that only hymns should be sung in church as they are the most holy (read: can be played softly on a piano or organ) and don't have those evil voodoo beats. You've probably also heard the counter-argument that most hymn tunes originated as a bar song. We've always wondered about this and decided to do a little digging into the history of some beloved hymns. (Note: All hymns come from the Seventh-day Adventist Hymnal, 1986 edition. Yeah, we're old school like that.) Now get ready to rock!
