Heino is considered by many an icon of kitsch in the English-speaking world. Heino resides in the small town of Bad Münstereifel where he owns a cafe, and plays his own music in the background. Bad Münstereifel is a historical spa town in the district of Euskirchen situated in the far south of the German state of North Rhine-Westphalia. In recent years, the unofficial Nintendo fan convention (NCON) has been held in the town's St. Angela Gymnasium.
Some of Heino's masterpieces are In einer Bar in Mexico, Carneval in Rio, Komm in meinen Wigwam, and Bier, Bier, Bier. HDV has heard rumors of a "Cosmic Order of Heino" cult, but their current whereabouts are unknown.
