PEG NICHOLSON was a good bay mare,
As ever trod on airn;
But now she's floating down the Nith,
And past the mouth o' Cairn.


Peg Nicholson was a good bay mare,
An' rode thro' thick and thin;
But now she's floating down the Nith,
And wanting even the skin.


Peg Nicholson was a good bay mare,
And ance she bore a priest;
But now she's floating down the Nith,
For Solway fish a feast.


Peg Nicholson was a good bay mare,
An' the priest he rode her sair;
And much oppress'd and bruis'd she was,
As priest-rid cattle are,—&c. &c.

Robert Burns
