Robert,
I don't recognize most of the songs you listed. I played at Bierkellars in Germany and other western European countries throughout the 80's. We did the traditional beer-drinking songs like:
Der mann am klavier
Du kannst nicht treu sein
In Munchen steht ein hofbrauhaus
Kornblumenblau
Kufsteinlied
Nach hause geh'n wir nicht
O du wonderschoner
Schneewalser
Solang der alte Peter
Trink, trink bruderlein
Waldeslust
Wer soll das bezahlen
Wiener praterleben
Alte kameraden
Der treue Husar
Deutschmeister Regimentsmarsch
Es war einmal ein treu'r Husar
Radetzky March
Tolzer Schutzenmarsch
I'm playing these same songs and others here (in America) at Oktoberfests and every German who attends recognizes every one of the songs I listed.
Is there a reason you didn't list these traditional songs that most older Germans know? Do they not play them anymore these days in Germany? I haven't been there in years.
Lucky
