The German lyrics, I think. Tho, German is barely fit for music. It always sounds like there’s a bit of phelm that could boil over at any moment. Tho I understand that folks in Latin America often confuse English for German and vice versa when they hear it spoken, so I suppose I shouldn’t poke too much fun. Teehehee
It is not surprising, since English is by far the largest Germanic language. The others are German and Dutch, plus their Scandinavian cousins Danish, Swedish, Norwegian, and Icelandic. To a speaker of a Latin based language, we are all still Germans. English does have an enormous vocabulary of words borrowed from the Latinate languages of course.
