Author of "다 나 의 서 노 래 하 자 (Come One and All, Come Join in Song)" in 찬송과 예배 = Chansong gwa yebae = Come, Let Us Worship In some hymnals, the editors noted that a hymn's author is unknown to them, and so this artificial "person" entry is used to reflect that fact. Obviously, the hymns attributed to "Author Unknown" "Unknown" or "Anonymous" could have been written by many people over a span of many centuries.
