This is another traditional hymn for Advent. The text is by Abbé Simon-Joseph Pellegrin (1663-1745), translated by Sister Mary of St Philip in 1877. The tune is VENEZ DIVIN MESSIE a sixteenth century French tune that is a 6/8 carol in the public domain.
I got the chords from OCP (GAB 346). The text in CWB II reverses “show your face” and “dispel the night” in the prechorus, an alteration that does not appear in any of the page scans in Hymnary nor any lyrics on line so I wonder if it was misremembered.
This is the tune from OCP.
This is the tune from CWB II without the octave leap at “hope” in the chorus.
