Holy Week - Laßt uns erfreuen herzlich sehr

We often hear the beautiful church organ play a tune listed in our hymnals as "Laßt uns erfreuen" all throughout the year with various hymns and sacred songs, which we learned is sourced from 1623's Ausserlesene, Catholische, Geistliche Kirchengesange, published in Köln in 1623.  And this is the original German tune, not the Ralph Vaughan Williams setting that what we know in our churches today and is easily identified by the location of the Alleluias.  The original song was an Easter tune, no less, "Laßt uns erfreuen herzlich sehr".  And it's a different arrangement than what we've heard in our lives for this Easter tune:

Laßt uns erfreuen herzlich sehr, Alleluia
Maria seufzt und weint nicht mehr, Alleluia
Verschwunden alle Übel sein, Alleluia
Jetzt glänzt der helle Sonnenschein, Alleluia
Alleluia!  Alleluia!  Alleluia!

Sag an, o freudenreiches Herz,Alleluia
Wo ist denn jetz, Ach, Weh und Schmerz? Alleluia
Glorreich vom Grab erstanden ist, Alleluia
Der Menschen Trost, Herr Jesu Christ. Alleluia
Alleluia!  Alleluia!  Alleluia!

O freudenreiche Osterzeit, Alleluia
Wo sich ein jeder Christ erfreut, Alleluia
Stimmt an den fröhlichen Jubelton, Alleluia
Singt alle, wer nur singen kann: Alleluia
Alleluia!  Alleluia!  Alleluia!

NOTE:  This translator doesn't do justice to the song metrically!

Let us rejoice heartily very, Alleluia
Mary sighs and weeps not, Alleluia
Be gone all evil, Alleluia
Now shines the bright sunshine, Alleluia
Alleluia! Alleluia! Alleluia!

Tell me, oh joy rich heart, Alleluia
Where is that book now, Oh, woe and pain? Alleluia
Is gloriously risen from the grave, Alleluia
The human consolation, Lord Jesus Christ. Alleluia
Alleluia! Alleluia! Alleluia!

O Joyful Eastertide, Alleluia
Where every Christian delighted Alleluia
True to the cheerful Jubelton, Alleluia
Sing all, who can only sing: Alleluia
Alleluia! Alleluia! Alleluia!
