Nun läßt uns dem Herren Dank sagenwas composed by Nikolaus Selnecker, its eight verses written by Ludwig Helmbold and was arranged by Johann Crüger.
I learned it as a bass singer with Die Zeitlupe sometime in 2006. This choir piece may be found in one of the Evangelishe Gesangsbücher as EG 320 and listed in Geoff's Choral Odds and Ends. .
