I have been looking all over for this masterpiece of Painters as it's my favorite & I finally unearthed it

Come hither, come hither, and sit for a spell
We have stories of murder and malice to tell
It is All Hallows' Eve and the Tower is bare
We bid you to enter! Come in if you dare!

What is that? It's a spook! No, it double I see!
There are two of them scaring the wits out of me!
Why, it's Ritchie and Eddie, the heirs to the throne
They were murdered in bed, not a soul heard 'em moan!

Who dunnit? King Richard? Some say it was so
Some think it was Margaret, but none of us know
Poor lads roam the halls of the Tower at night
Bemoaning the state of their miserable plight

But listen! There's more! Can you hear a lass cry?
Why, it's Lady Jane Grey! She was too young to die!
It was off with her head when they made her a queen,
Beheaded not long after turning sixteen

Poor Jane met the axe after only nine days
And Mary took over with bloodiest ways
She burned all her enemies! Fried 'em like eggs!
And tied 'em up tight with a rope on their legs

But Jane's not the only poor queen with no head
Don't forget Anne Boleyn with a daughter instead
Her hubby decided he wanted a son
So he cut off her head when she didn't have one

Then later when Henry was old and quite worn
He married Cate Howard, a rose without thorn
But he got himself pricked and cut off her head
When the rose and her lover were found in a bed

This is only the teaser! The Tower has more!
It's inviting you in, so just open the door....
Take a very deep breath, there are no guarantees
That you'll come out alive, so come in, if you please....
