The younger sister of the composer Imre Kalman was once asked:
How does your brother create his wonderful operettes?
The girl replied so:
My brother and his freelancers meet daily. Every day they drink a few liters of black coffee, smoke an infinite number of cigars, tell each other jokes and whisper on the whole house, then talk long about the weather, about girls, about politics... At the same time they all the time argue, quarrel and scream. So it continues day after day for many months... And suddenly one day the brother reports that the operetta is ready...
