It took me some time but I finally was able to decipher the hymn.
It is the famous Latin hymn Salve Regina
Priest: Salve, Regina!
People:
Mater misericordiae, etc.
Latin Version:
Salve, Regina, Mater misericordiae,
vita, dulcedo, et spes nostra, salve.
ad te clamamus
exsules filii Hevae,
ad te suspiramus, gementes et flentes
in hac lacrimarum valle.
Eia, ergo, advocata nostra, illos tuos
misericordes oculos ad nos converte;
et Jesum, benedictum fructum ventris tui,
nobis post hoc exsilium ostende.
O clemens, O pia, O dulcis Virgo Maria.
English Version:
Hail, holy Queen, Mother of Mercy,
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.
