Sunday is the Feast of All Souls where we remember those who have died.
Here is a setting of part of a requiem--a funeral Mass--by John Rutter. The lyrics (and translation when necessary) are posted under the video.
I heard a voice from heaven saying unto me
blessed are the dead who die in the Lord
for they rest from their labours.
Even so saith the Spirit, for they rest.
Lux aeterna luceat eis Domine
cum sanctis tuis in aeternum:
quia pius es.
Let everlasting light shine on them, O Lord
with your saints for ever:
for you art merciful.
dona eis, Domine;
grant to them, Oh Lord;
