Sleep little one
The old ogre has a gun
The owl at the zoo
will keep an eye on you
Ghosts in your head
and a banshee on your bed
Don't hear what they say
don't you trust what they play
You'll only hear my music box

Came the householder
and cried on my shoulder
Came a contender
returned it to the sender
Saw it on the news
there's a killer on the lose
Don't hear what they say
don't you trust what they play
You'll only hear my music box

Believed in a god
turned out he was a fraud
I found a buyer
turned out he was a liar
I give you a haven
Protect you from the craven
Don't hear what they say
don't you trust what they play
You'll only hear my music box
