In this stately scottish Jacobite song a young man is encouraged to tilt his beaverskin hat at a rakish angle as he rides off to fight the English.

This is not the best played version but the video is good for remember it after a longer time 😉

Lyrics:
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!
