The melody for LASST UNS ERFREUEN is named for the Easter text “Lasst uns erfreuen herzlich sehr” in the Jesuit hymnal Ausserlesene Catlwlische Geistliche Kirchengesänge where it was first published in Cologne in 1623. The setting by Ralph Vaughan Williams first published in The English Hymnal in 1906 has become the most popular version of the tune paired with the text “Ye watchers and ye holy ones” by Athelstan Riley. Other texts often paired with the melody include “All Creatures of our God and King” and “From All That Dwell Below the Skies.”
Hyfrydol is a Welsh hymn tune composed by Rowland Prichard in 1844. It was originally published in the composer’s handbook to the Lutheran Hymnal Cyfaill y Cantorion (“The Singers’ Friend”). The best-known arrangement is probably that by Ralph Vaughan Williams, which he originally produced for his revision of the English Hymnal. Popular texts paired with this tune include William Chatterton Dix’s hymn Alleluia! Sing to Jesus!, Charles Wesley’s Love Divine, All Loves Excelling and Come Thou Long-Expected Jesus, Francis Harold Rowley’s (1854-1952) I Will Sing the Wondrous Story (1886), John Wilbur Chapman’s Our Great Savior (“Jesus, what a friend for sinners”) (1910), and Philip P. Bliss’ I Will Sing of My Redeemer (1876), as well as many other hymns from a variety of faith traditions.
