The chorus of that song is, "Sometimes the snow comes down in June, sometimes the sun goes 'round the moon." Although I'm aware of that, I have always, since pretty much the first time I heard that song, sung, "Sometimes the sun goes down in June, sometimes the snow goes 'round the moon."
Because, you see, for a girl who grew up in Alaska, it is no more unlikely that snow should go around the moon than it is that the sun should set in June.
That is all. :)
