I could have figured out that that was the line from the hymn, but yeah. I can see that, mostly because I grew up going to unprogrammed Quaker Meeting, which consists almost entirely of silence. I think not everyone knows the same hymns, and partly it's sad, partly that's what hymn-books are for. I'm not much of a Christian, but I'm kind of ... culturally Christian. I'd sing the hymns if I knew them.
