I personally love the old German songs and sing them in horrible German. I think they need to be preserved and sung. If a song was written especially for the THird Reich though I think it should be left unsung..unless it was about homesickness, the girl he left behind or something universal. We ahve some great German singers where I live and at least one German family sent to relocation camp in WWII. We certainly should sing the old songs from Germany in USA where so much of our population was of German ancestry..and they were treated quite badly especially in WWI. mg
