A famous man was Robin Hood,
The English ballad-singer's joy,
But Scotland has a chief as good,
She has, she has her bold Rob Roy.
A dauntless heart Macgregor shows,
And wondrous length and strength of arm;
He long has quell'd his Highland foes,
And kept, and kept his friends from harm.
A famous man, &c.
His daring mood protects him still,
For this the robber's simple plan,
That they should take who have the will,
And they, and they should keep who can.
A famous man, &c.
And while Rob Roy is free to rove,
In summer's heat and winter's snow,
The eagle he is lord above,
And Rob, and Rob is lord below.
A famous man, &c.
