You may not know too much about Berlin operetta, but even when you’re not a native German, chances are high that you know Berlin’s unofficial anthem “Berliner Luft”, or “Berlin Air”. Chances are that you can also sing and dance along to waltzes and non-military marches whose choruses go “Luft, Luft, Luft” or “mop, mop, mop”.
