Vaughn Williams really was the perfect composer for the English Hymnal. So much of his music (including this tune) is based on traditional English folk song, so it's organically English and fits the rhythm of English speech to a "T". His 4 part setting of the "Magnificat" with the old Prayer Book words is perfection.
Another of my favorites of his is “For All the Saints” (especially with all the verses). It’s so inspiring, plus it has one of those melodies that never ends ... like our pilgrimage here on earth...
