Saluton! I just discovered this thread as I recently started to learn Esperanto and was curious to know if there was an Esperanto translation of the song Dona Dona. It was my father, Arthur S. Kevess (1916-1973), who wrote the original English translation of the Yiddish song, more than 40 years ago. I remember him putting the finishing touches on his translation and singing it to us. He was thrilled when Joan Baez performed it. We are still receiving royalty statements listing performances on a regular basis all over the world. Most, if not all of the subsequent translations into other languages appear to have been based on my father's English translation; they all appear to leave the refrain "Dona Dona Dona" untranslated, which makes sense to me. I plan to search in my father's papers to see if I can find any more information on this point. If I do, I will certainly post it here.
