It's being done in a CHURCH, not on a concert stage. No real tune? maybe not one you're familiar with, but those singing it seemed to get on all right. Not being a Christian, I probably wouldn't sing it myself, but I heard a nice tune and some good harmonies in there, so I might have a go at adapting it.

Is the standard "If I don't like it, it's not music?" I don't mean to pick, as Mrs. Tootler has a right to her opinions. Perhaps your question could have been better phrased?
