Over half my life ago when I was a religious fundamentalist in the church of Christ, I led this song for the congregation on a Wednesday night service since it was in our hymnnal. I liked the history that came with it: it was a song about the faithful triumphing over oppression.
A few weeks later, it was fully censored in all of the books. In my naïvete I hadn't realized that there was still a whole bunch of Confederate sentiment in Texas. It had never occurred to me that the song might be controversial.
