Robert Burns
Johnie Lad, Cock Up Your Beaver
1791
When first my brave Johnie lad came to this town,
He had a blue bonnet that wanted the crown;
But now he has gotten a hat and a feather,
Hey, brave Johnie lad, cock up your beaver!
Cock up your beaver, and cock it fu' sprush,
We'll over the border, and gie them a brush;
There's somebody there we'll teach better behaviour,
Hey, brave Johnie lad, cock up your beaver!
Severely bored today so went through some books from grad school and came across this.
