I'm awfully pleased that no-one's mentioned "Wir Fahren Gegen England" yet, but that's possibly because, with new Celtic words, it has since been adopted as an Irish March!Seriously, though, who was "Horst Wessel"? I have a vague memory that there is/was a sailing ship of that name. Perhaps that was the "Horst Vessel"!
Gruss Gott!
