Betty Smith sings a version of "Little Margaret" to the tune of "Shady Grove":

LITTLE MARGARET
(as sung by Betty Smith)

Little Margaret sitting in her high hall chair
A-combing her long yellow hair
She saw Lord William and his new-made bride
Riding down the road so near.

She threw down her ivory comb
She threw back her long yellow hair
And out of the room this lady ran
She was never anymore seen there.

It was all lately in the night
When they were fast asleep
Little Margaret appeared all dressed in white
A-standing at their bed-feet.

It's how do you like your snow white pillow
And how do you like your sheets
And how do you like the new-made bride
That's lying in your arms asleep?

It's fine I like my snow white pillow
And it's well I like my sheets
But best of all's the fair young maid
That's standing at my bed feet.

He's called the servant for to go
And saddle the dappled roan
He's rode to Little Margaret's house that night
And knocked on the door alone.

Oh is Little Margaret in the house
Or is she in the hall?
Little Margaret's in her coal-black coffin
With her face turned towards the wall.

Fold back, fold back those ivory shrouds
Be they ever so fine
I want to kiss those clay-cold lips
They'll never anymore kiss mine.

It's once he's kissed her snow-white brow
And twice he's kissed her cheeks
Three times he's kissed her clay-cold lips
And he fell in her arms asleep.

This is from memory and may have some differences to the way Betty sings it. (Note the ancient belief that it's death to kiss the dead.) I also sing a longer version from Cecil Sharpe; when William wakes after the ghostly visitation, he says "I dreamed the room was filled with swine and my bride a-floating in blood."
