I recently added Adolf Burkhardt's Esperanto version of the "Arbetloze Marsh" to my online hymnal (it's part of his song booklet, Pli ol kvindek, which I'm putting online as a memorial to him). Adolf was a German Lutheran pastor who died early this year. He was in many ways my mentor in Esperanto hymnody (he edited the two most important Esperanto Christian hymnals). And he also translated a number of songs from Yiddish (others will be coming online soon, as I type them and find the MIDIs).
