Hymns

For some time, the richness of the hymns sung in church has piqued my curiosity.  By hymns, I include the psalms, the canticles, such as the Benedictus and the Magnificat, the ancient hymns, as the Trisagion, the hymns of St. Thomas Aquinas, those of John Wesley, and hymns of more recent times.  As Google's Blogger allows posts to be updated, I don't know where this post will lead.

For starters, today we sang a hymn by Omer Westendorf, whose life was entirely in the 20th century, with a Welsh melody.  In searching for his biography, I came upon this most interesting site from Collegeville.
