Lyrics and notes from Traditional Ballad Airs ... Volume 1, edited by William Christie (Edinburgh: Edmonston & Douglas, 1876), page 276. There is also sheet music on that page:

The Editor arranged this Air from two sets,—one sung by his paternal grandmother to “The bonny Lass o’ Fyvie,"—the other sung to “Barbara Allan" by his maternal grandmother. The Ballad is given from the recitation of a native of Monquhitter, with some alterations from a native of Banffshire, who knows many of the traditional Ballad Airs and Ballads sung in the three north-eastern Counties of Scotland. He was of opinion that the Ballad was composed after a company of Dragoons had escorted the O’Connors to Fort-George, who had been engaged in the Irish rebellion in 1798. If so, this would account for the “Irish Dragoons" in the Ballad. The Dragoons may have been at “Lewes of Fyvie" on their way to, or from Fort-George. The Ballad and Air are still known in different forms in the Counties of Aberdeen and Banff. Eight lines of the ballad are omitted.

THE BONNY LASS O' FYVIE

Green, green grows the birks on sweet Ythan side,
And low lies the bonny Lewes o' Fyvie;
In Fyvie there's bonny, in Fyvie there's braw,
In Fyvie there's bonny lasses mony.
There cam' a troop o' Irish Dragoons,
And they were quarter'd in Fyvie;
Their captain has fa'en in love wi' a lass,
That by a' was ca'd pretty Peggy.

"Come down the stair, pretty Peggy," he said,
"Come down the stair, pretty Peggy;
"Come down the stair, comb back your yellow hair,
Tak' fareweel o' your mammy and your daddie.
What would your mammy think to hear the guineas clink,
And the hautboys playing before you?"
"Little would my mammy think to hear the guineas clink,
If I follow'd a soldier laddie."

"A single soldier's wife you shall never be,
For you'll be the captain's lady;
I'll make my men stand with their hats in their hand,
In the presence of you, pretty Peggy."
But the colonel he cried, "Come, mount, boys, mount,"
The captain he cried, "Let us tarry;
Oh, gangna awa' this day yet or twa,
Till we see gin the bonny lass will marry."

"I've gi'en you my answer, kind sir," she said,
"And you needna ask me nae farther;
I do not intend to go to a foreign land,
And I'd scorn to follow a soldier."
Then out did speak the drum-major's wife:
"Oh dear, but ye are saucy.
There's mony a bonnier lassie than you,
Has follow'd a soldier laddie.

"But gin I were on my high horse set,
And riding on to old England,
I would ne'er turn my horse's head about,
For a' your Fyvie women."
Then the pipes play'd on by Ythan side,
Awa' frae the bonny Lewes o' Fyvie;
And every man on horseback did ride,
But behind them they left pretty Peggy.

And ere they cam' to the brig o' Dyce,
They got their captain to carry;
And when they cam' to bonny Aberdeen,
They got their captain to bury.
He was ca'd Captain Ward, and he died on the guard.
He died for love of pretty Peggy;
And said, "When I am gone, you'll let it be known,
That I died for the bonny lass o' Fyvie."
