As I remember it, there is one more verse:

Now when Lily White Sands he heard the news,
Both his eyes ran down with water;
Says he, "In love I'll constant prove,
Blow me if I live long after."
So he cut his throat with a piece of glass,
And he stabbed his donkey after;
So the donkey and Lily White Sands both died,
For love of the rat-catcher's daughter.
Deedle dum etc.
