8 looks like an interpolation, and very probably the ballad was docked at the beginning in order to suit the parlor better.
FOOTNOTES:
[181] All the genuine ones. 'Lady Anne,' in Scott's Minstrelsy, III, 259, 1803, is on the face of it a modern composition, with extensive variations, on the theme of the popular ballad. It is here given in an Appendix, with a companion piece from Cromek's Remains of Nithsdale and Galloway Song.
[APPENDIX]
LADY ANNE
"This ballad was communicated to me by Mr Kirkpatrick Sharpe of Hoddom, who mentions having copied it from an old magazine. Although it has probably received some modern corrections, the general turn seems to be ancient, and corresponds with that of a fragment [B b], which I have often heard sung in my childhood." Minstrelsy of the Scottish Border, III, 259, ed. 1803.
Buchan, Gleanings, p. 90, has an additional stanza between 8 and 9 of Scott's, whether from the old magazine or not, it would not be worth the while to ascertain.
Cunningham, Songs of Scotland, I, 339, has rewritten even 'Lady Anne.'
