Here it is: written by Roy Williamson of The Corries: it doesn’t mention the date, but the history books will tell you that the battle was in September!

THE BATTLE OF PRESTONPANS                         Roy Williamson

The chevalier, being void of fear,
Did march up Birsley Brae, man,
Through Tranent, ere he did stint
As fast as he could gae, man.
General Cope did taunt and mock
Wi’ many a loud hussa, man,
But ere next morn proclaimed the dawn
We heard anither craw, man.

Chorus
General Cope led frae behind
Tae keep his men in order,
When the English ran, he was in the van
And first across the Border.

The brave Lochiel, as I heard tell
Led Camerons on in clouds man,
The morning fair, and clear the air
They loosed with devilish thuds man.
Down guns they threw, and swords they drew
And soon did chase them off, man,
On Seaton Crafts, they buffed their chafts
And gart them run like daft, man.                Chorus

Now Caddell dressed among the rest
Wi’ gun and guid claymore, man,
On gelding gray, he rade the day
Wi’ pistols set before, man.
The cause was good, he’d spend his blood
Before that he would yield, man,
But the night before, he left the corps,
And never faced the field, man.                Chorus

Now Simpson keen tae clear his een
O’ rebels far in wrong, man
Did never strive wi’ pistols five
But he galloped wi’ the throng, man,
Ower Sutra Hill, e’er he stood still
Before he tasted meat, man,
Monteith may brag, o’ his swift nag
That bore him aff sae fleet, man.                Chorus

The bluff dragoons swore blood and oons
They’d mak the rebels run, man,
Yet they flee, when them they see
And they winnae fire a gun, man,
They turned their back, their foot they brak,
Terror seized them a’, man,
Some wet their cheeks, some filled their breeks
And some for fear did fa’, man.                 Chorus
