Andy,
in case you mean this song it's really worth posting and I shall let you do it. It is one of the very few German language songs I ever considered posting. However, it is not a German song in origin, for it comes from Latvia (or Lithuania). Pete Seeger is on record for having said or written that he had read a few lines in a Russian book that gave him the idea for his 'Where have all the flowers gone'. It is probable that this is the song involved.
