Heighho! who's above?

Heighho! who's above?
Nobody's here but me, my love.
Shall I come up and say how do?
Aye, marry, and thank you to.
Where's your governess? She's a-bed.
Where's the key? Under her head.
Gently trip and bring it here,
And let me in to you, my dear.
The dog will bark, I dare not stir.
Take a halter and hang the cur.
No, no. Why, why?
'Cause not for a guinea my dog should die.
