The music for the 2nd Lenten Preface is available in the Missal. Here it is recorded by Fr Michael Hutson.
The Lord be with you: And also with you.
Lift up your hearts: We lift them up to the Lord.
Let us give thanks to the Lord our God: It is right to give him thanks and praise.
Father, all-powerful and ever-living God,
we do well always and everywhere to give you thanks.
This great season of grace is your gift to your family
to renew us in spirit.
You give us strength to purify our hearts,
to control our desires,
and so to serve you in freedom.
You teach us how to live in this passing world,
with our heart set on the world that will never end.
Now, with all the saints and angels,
we praise you for ever:
