There is a German comic folk(?) song which was sung by Richard Dyer-Bennett, called Nu Ja Ja. "Nu Ja Ja" is a sort of chorus line which keeps coming back. It seems that a young man named Krenzlkraut is courting a madchen named Rosl, asking her to marry him. In effect she says she's too young to marry. He replies something to the effect that if she's too young to marry he will be--what? I don't understand enough of the German to be sure. In any case, this impresses her, and yes, she'll marry him.
I'd love to get ahold of the complete German text and a translation. Can anyone help?
