Freda and Wwwilliam, those are great!

My contribution:

The bishop and the witch

A bonny young witch to the cemetery gaes
To work her charms among the graves
Sae lang she staid and waited lang
For the moon to rise to the spells she sang

The moon at last deigned to appear
But the starry sky refused to clear
Thae billow'd clouds hid the witches light
She must carry on in the darkest night

Beneath the hallowed Christian gound
An ancient Bishop, he lay bound
An' at his side, Saint Pat's bacuill
The same had pierced that old Laoghaire

An' as the witch began her chants
The Bishop's bones began to dance
So sweet and lively was her song
The bones were moved to dance along

The Bishop's spirit, long asleep
Awoke to find his bones a-leap
An angry prelate he was then
An' so did work to be her bane

Above the earth the witch unsheathed
Her shining sword, the airs to cleave
So as she swung it broad and high
The Bishop's ghost did hover nigh

An' whether the Bishop's sharp bacuill
Or a chancy slip of her own true will
All in the dark when the sword came down
her own dear blood did speckle her gown

"OW! Ow!!" she cried at this painful deed
While her pretty little foot did quickly bleed
An' seeing now the Bishop's ghost
Knew that her good night's work was lost

"A curse on thee, thou Bishop cruel
An' on Saint Patrick's old bacuill
I did no harm to your mouldy bones
They danced on their own to my dulcet tones!"
