Poulenc: Salve Regina

It's:

Francis Poulenc's setting of Salve Regina. Performed at the Solemn Mass on Christmas Eve 2011 by the choir of the Church of Saint Mary the Virgin, New York City. James Kennerley, Organist and Music Director.

Lovely! Here are the words in Latin and English from CPDL (which notes that "Salve Regina are the opening words of one of the four Breviary anthems of the Blessed Virgin Mary. It is said from the First Vespers of Trinity Sunday until None of the Saturday before Advent."):

Salve Regina, Mater Misericordiae,
Vita, dulcedo, et spes nostra, Salve!
Ad te clamamus, exsules filii [H]evae,
Ad te suspiramus, gementes et flentes,
In hac lacrimarum valle.
Eja ergo, Advocata nostra,
Illos tuos misericordes oculos ad nos converte
Et Jesum, benedictum fructum ventris tui,
Nobis, post hoc exilium, ostende,
O clemens, O pia, O dulcis Virgo Maria.

Hail, Holy Queen, Mother of mercy,
[Hail] our life, our sweetness and our hope!
To thee do we cry, poor banished children of Eve,
to thee do we send up our sighs,
mourning and weeping in this valley of tears.
Turn, then, most gracious advocate,
thine eyes of mercy toward us,
and after this, our exile,
show unto us the blessed fruit of thy womb, Jesus.
O clement, O loving, O sweet Virgin Mary.
