This is a song about a folk musician who makes people dance until they drop dead.

It's saturday evening in the village and the youth have, as usual, come to dance upon the village ridge(?)...
When suddenly the music stops and a new folk musician appears out of the darkness, wearing a dark hat and sporting two fiery eyes...
He begins playing, and the youth start dancing more wildly as he plays, and it soon dawns on them that it's the evil one himself who's leading the dance...
