The Dransfields did a version of this song on 'Lord of All I Behold', one of those great albums still in the clutches of the dreaded Bulmer. It is similar to the Carthy version posted above by Wolfgang, but I reckon the numerous minor textual variations and different ending warrant its posting. Unfortunately, no source is given.

BOLD WILLIAM TAYLOR

I'll tell you a story about two lovers
O from Lichfield town they came
The young man's name was William Taylor
Sally Gray was the maiden's name

William Taylor he is listed
For a soldier he is gone
He has left his own true lover
For to sigh and for to mourn

Sally's parents they did despise
Filled her heart with grief and woe
And then at last she vowed and promised
For a soldier she would go

So she dressed herself in man's apparel
Man's apparel she put on
Then off to seek Bold William Taylor
For to seek him she has gone

One day as she was exercising
Exercising, one, two, three
A silver chain pulled down her waiscoat
And exposed her lilywhite breast

So the sergeant-major he stepped up to her
Asking what brought her here
I've come to seek my own true lover
Who has proved to me severe

Well, if you've come to seek your own true lover
I pray you tell to me his name
His name it is Bold William Taylor
And from Lichfield town he came

Well, if his name be William Taylor
William Taylor he is not here
He's lately married a rich young lady
Worth ten thousand pounds a year

If you rise early in the morning
Just before the break of day
It's there you'll spy Bold William Taylor
Walking out with his lady gay

So she rose early in the morning
Just before the break of day
And there she spied Bold William Taylor
Walking out with his lady gay

So then she's called for a sword and pistol
That was brought at her command
She fired and shot Bold William Taylor
With his bride at his right hand

Well then the captain he stepped up to her
Pleased well at what she had done
He took her and made her a bold commander
Of a ship and all the men
