Here are the lyrics Kate Rusby sings:

THE WHITE COCKADE

One day as I was walking all o'er yon fields of moss
I had no thoughts of enlisting till some soldiers did me cross
They kindly did invite me to a flowing ball and down
They advan-ced, they advan-ced me some money
A shilling from the crown

My true love he is 'listed and he wears a white cockade
He is a handsome young man, likewise a roving blade
He is a handsome young man, he's gone to serve the King
Oh my very, oh my very
Heart is aching all the love of him

My true love he is handsome and comely for to see
And by a sad misfortune a soldier now is he
I wish the man that's listed him might prosper night nor day
And I wish that, I wish that
The hollanders might sink him in the sea

Then he took out his handkerchief to wipe my flowing eye
Leave off your lamentations, likewise your mournful sighs
Leave off your grief and sorrow until I march o'er yon plain
We'll be married, we'll be married
In the springtime when I return again

My true love he is handsome and it's all for him I'll rove
I'll write his name on every tree that grows in yonder grove
My poor heart it does hallow, how my poor heart it does cry
To remind me, to remind me
Of my ploughboy, until the day I die
