OK, I just read that the German Panzerlied is still sung today in the German Bundeswehr (=army) although it was quite popular during WWII. They had to skip some strophes which were too National Socialist. Like we do with our German national anthem. We only sing the third strophe and never the first two strophes since they contain stuff like "Germany, Germany above everything in the world" and so on. The complete text would be like this:
    Das Lied der Deutschen
    Deutschland, Deutschland über alles,
    Über alles in der Welt,
    Wenn es stets zu Schutz und Trutze
    Brüderlich zusammenhält,
    Von der Maas bis an die Memel,
    Von der Etsch bis an den Belt –
    |: Deutschland, Deutschland über alles,
    Über alles in der Welt!
    Deutsche Frauen, deutsche Treue,
    Deutscher Wein und deutscher Sang
    Sollen in der Welt behalten
    Ihren alten schönen Klang,
    Uns zu edler Tat begeistern
    Unser ganzes Leben lang –
    |: Deutsche Frauen, deutsche Treue,
    Deutscher Wein und deutscher Sang!
    Einigkeit und Recht und Freiheit
    Für das deutsche Vaterland!
    Danach lasst uns alle streben
    Brüderlich mit Herz und Hand!
    Einigkeit und Recht und Freiheit
    Sind des Glückes Unterpfand –
    |: Blüh im Glanze dieses Glückes,
    Blühe, deutsches Vaterland!
Don't worry, if there is one thing that German grandpas like to tell their grandchildren, it's their experiences in WWII. We've talked a lot about that. 
My mother's dad served in the German air force as a reconnaissance pilot, my father's dad was in the Germany marine corps stationed for a long time in Norway where the U.S. troops destroyed his ship and arrested him and his crew. 
I'll see if I can find some pics.
