Actually, Euph, I think only the third namby-pamby, touchy-feely 'Einigkeit und Recht und Freiheit' verse is the 'Official' Federal Republic anthem since the War. Apparently due to past associations the use of even the tune itself is still a matter of some controversy among the German equivalents of our DUmmies and other mixed-nut Democrats.
An interesting feature of those German Blasmusik and Volkslieder in general is that there are some familiar tunes and musical phrases that are used in more than one context, for instance parts of the Imperial Fridericus Marsch and a few if the folk songs sound to me to have been recycled in various Nazi pieces, the Panzerlied and the folksong Lusika use the same sheet music, and the folk song An die Nordseekueste also uses the same music as the Irish folksong Wild Rover.
Ah, okay, being an instrumentalist, I don't pay attention to the words anyway!

And regarding the Blasmusik and Volkslieder, about all I can remember any more is that tune
Hoch die Tassen!. In all honesty, we didn't do too much of that stuff in Berlin except one gig on Rosenmontag. How many times can you blast a Bb major chord?

Some of the Army marches I remember, though:
Bayerischer Defiliermarsch; Marsch aus Petersburg; and the big tune of all time,
Alte Kameraden.
Speaking of mamby pamby, in lieu of the German national anthem, what we played in Berlin almost exclusively was
Berliner Luft - a dumbass tune with some ****ing whistling in it. Dopey, but the Berliners loved it.
