With a littlehelp from Gregg Butler of Strawhead here are the lyrics as he used to sing them;

The Saucy Prince's Own

Twas on the 1st of August when from Cadiz we set sail
As many a gallant Frenchman has good reason to bewail
Straight into Gibraltar Bay our gallant fleet did stear
And on the Saturday we went ashore at Al Gesir (Algesiras)

Oh we are the lads of honour boys
Belonging to the crown
And death to those who dare to oppose
The Saucy Prince's Own

Well we marched along the coast until we reached Tarifa Bay
While waiting for the Spaniards in a convent there we lay
But when the Spaniards joined us there we marched both night and day
Determined when we met the foe to show them British play

Oh we are the lads..

The Spaniards took the front me boys their country for to free
And bid our lads pick up the rear this glorious sight to see
But when the Barossa's plains appeared we never saw them more they
Their column went behind the woods along Saint Agnes' shore

Oh we are the lads..

But Graham our commander didn't know of their design
And he swore the British infantry should never stay behind
But as we marched to join the Dons not dreading any stare
The Frenchman in an ambush lay and closed upon our rear

Oh we are the lads..

Oh turn your face about my boys for Britain show no fear
Extent your front me Irish lads and keep your outflanks clear
Remember Cape Trafalgar where Lord Nelson bled before
The blood that triumphed on the sea shall conquer on the shore

Oh we are the lads..

Well we charged into the ranks me boys their ranks were over thrown
And in confusion forced to fly before the Prince's Own
Their generals left behind them their guns, their eagles too
While brave hisannah's cheered and charged and boldly did pursue

Oh we are the lads..

Here a health to Goff and Graham, who faught all on that field
And though they fought them ten to one they got their foes to yield
They left them in confusion and their eagles took away
Lord made our Irish lads to cheer on each hurrah today

Oh we are the lads.. x2
