Listening to When the Wild Wind Blows, I came to associate the line "have you heard, have you heard" with the character Krösa-Maja. Those familiar with the Swedish children's books about Emil i Lönneberga (or the filmatized version) will know what I mean
(Of course, I assume that only people from the Nordic countries would know those books, don't know how popular they were in e.g. Germany?)
Super popular in Germany. Half my children's books were from Sweden. I know I read it as a kid, but I'm not sure I remember what you're referring to.
