Be Thou My Vision is one of my favorite hymns. =)
Here are my brother and I playing it as a duet with the piano and violin (you can see his bow bobbing in and out of view). =) Read an exposition and history of the song here, as part of A Still Small Voice’s Hymn History Event.
“Thou wilt show me the path of life: in thy presence is fulness of joy; at thy right hand there are pleasures for evermore.” ~ Psalm 16:11
