This tune was more familiar than I expected to be:

  X:0
  T:Ne maram Gorjanca
  S:Zbrala Dusica Kunaver, Slovenian Customs and Songs, 2003
  M:3/4
  L:1/4
  Q:3/4=60
  K:EPhr

It's almost the same as the tune for the Serendipity Singers' 1960s song "Beans in our ears", which I think was written by Pete Seeger.

Where did Seeger get it from?
