Music on a Sauer organ part 3

Third exploration of this Sauer organ with (as usual) works of less know composers.
The first one is Friedrich Wilhelm Franke (1862-1932), teacher at the Hochschule in Köln. He published in 1920 a "Neues Choralbuch" that I discovered with great pleasure. In all pieces, the tenor part plays the melody. All works fine on this organ.

1. Ach Gott und herr
2. Ach Gott vom Himmel 0:50
3. Allein Gott 1:52
4.Herlich tut mich 3:03

The second composer is Victor Klauss (1805-1881). He belongs to the romantic German tradition.
5. Allegro maestoso 4:22
