Grishka, we sing it in worship at least twice a year at my church in Seattle, more often when we have hymn sings or loosely designed evening services, and the sense in which we sing it has little to do with the War of 1861-65. It is a living Christian hymn as well as a historical monument. I disapprove of the selection of stanzas we sing, but I approve of the use of it in general by my church. And musically it's often a very powerful rendition, sometimes in 2:4 but more often in 3:4 time.
