Fah...who needs all these warm sweet fuzzy songs of true and constant adoration? Give me a good bitter song of betrayal and murder any day ;oP

One of my personal favorites: The Twa Corbies. Pardon the terrible attempts at the accent and getting any words wrong this is from memory.

As I was walkin' all alane
I heard twa corbies mak a mane
An' one a'them tae the other did say-o
Where will we gang an' dine the day-o
Where will we gang an' dine the day?

On 'ahind o' a long fail dike
I wot there lies a new slain knight
Nabody kens that he lies there-o
But his hawk an' hound and his lady fair-o
His hawk and hound an' his lady fair

His hawk is tae the hunt an' gone
His hound tae bring a wild fowl hame
His wife ha' taken another mate
Sae we can mak our dinna sweet-o
We can mak our dinna sweet

An' you can sit on his white breast-bone
An' I'll pick out his bonny blue een
An' with a lock of his yella hair-o
We'll theek our nest when it grows bare-o
We'll theek our nest when it grows bare

An' many's a one for him maks mane
Naebody kens where he is gane
Through his white bones when they grow bare-o
The wind shall blow forever mair-o
The wind shall blow forever mair

She's Like The Swallow comes in a very close second. And there was another song...or perhaps it was a poem? *puzzled* Something like An' where ha' ye been Lord Roland my son?/An' where ha' ye been my handsome young man?/I have been to the wild woods Mother make my bed soon/For I'm weary with huntin' an' fain wald lie down.
