One notable difference between the DT version and the Greig-Duncan version of the song.

This is from the Digital Tradition:

This pretty fair maid fell a-trembling with fear
Not knowing where to run or how to get clear
But as he was a-fumbling a-feeling for his knife
This pretty fair maid she took away his life

This is from Greig-Duncan:

This pretty fair maid fell trembling with fear
Not knowing where to wander or where for to fly
But as he was a-fumbling a-feeling for his knife
This pretty fair maid she took away his life
