Firethief lyrics

Who stole the heart of my bonnie laddie?
All alone and aloney O
And left me another lad in his body
Down where I cannot go
Down where I cannot follow
Who stole the light from my laddie's eyes
And left me another lad in disguise?
Who stole the words that were on my laddie's tongue
And left me a rickle of skin and bone?
Who stole today? Who stole tomorrow?
And left me with nothing but doul and sorrow?
I know the name of the fire thief
But you can't grow a tree from a fallen leaf
