Actually it was one version of Earl Bran that Sir Walter Scott had courtesy of the Laidlaws. To be clear, here it is:

Earl Bran- Laidlaw- (22 d. Abbotsford) Child A
Child A."Scotch Ballads, Materials for Border Minstrelsy," No 22 d. In the handwriting of William Laidlaw. Scott has written at the head, Earl Bran, another copy. At the time when Sir Walter Scott was collecting the materials for this work, the farm of Blackhouse was tenanted by the father of his attached friend, and in latter days factor (or land-steward), Mr. William Laidlaw.

EARL BRAN

1 Earl Bran's a wooing gane;
Ae lalie, O lilly lalie
He woo'd a lady, an was bringing her hame
O the gae knights o Airly

2 . . . . .
They met neither wi rich nor poor.

3. Till they met wi an auld palmer Hood,
Was ay for ill, an never for good.

4. 'O yonder is an auld palmer Heed:
Tak your sword an kill him dead.'

5 ' Gude forbid, O ladie fair,
That I kill an auld man an grey hair.

6 'We'll gie him a an forbid him to tell;'
The gae him a an forbad him to tell.

7. The auld man than he's away hame,
He telld o Jane whan he gaed hame.

8 'I thought I saw her on yon moss,
Riding on a milk-white horse.

9. 'I thought I saw her on yon muir;
By this time she's Earl Bran's whore.'

10 Her father he's ca'd on his men:'
Gae follow, an fetch her again.'

11 She's lookit oer her left shoulder:'
O yonder is my father's men!

12 'O yonder is my father's men:
Take my cleadin, an I'll take thine.'

13 'O that was never law in land,
For a ladie to feiht an a knight to stand.

14 'But if yer father's men come ane an ane,
Stand ye by, an ye'll see them slain.

15 'If they come twae an twae,
Stand ye by, an ye'll see them gae.

16 'And if they come three an three,
Stand ye by, an ye'll see them die.'

17 Her father's men came ane an ane,
She stood by . . .

18 Than they cam by twae an twae,. . . . .

19 Than they cam by three an three,. . . . .

20 But ahint him cam the auld palmer Hood,
An ran him outthro the heart's blood.

21 'I think I see your heart's blood:''
It's but the glistering o your scarlet hood.'
