Whatever the case, “Szomorú Vasárnap,” as it was titled, didn’t make much of a splash at first. But two years later, a recorded version by Pál Kálmar was connected to a rash of suicides in Hungary. The song was then allegedly banned. Short of learning Hungarian and trawling through Budapest newspapers from the 1930s, it is impossible to verify any of this (Hungary does historically have one of the higher suicide rates in the world - approximately 46 out of every 100,000 people take their own lives there every year).
