Stewie, the text you posted seems to be a composite taken from several versions. The first stanza is from no. 157A (Huntington Libary. Christmas carolles newley Imprnted (Richard Kele) c. 1550; p. [31]), the second & third from no. 157B (Bodleian Library. MS. Eng. poet. e. I; XV century), the fourth from no. 157A(?), and the fifth & sixth from no. 158 (Balliol College, Oxford, MS. 354; XVI century). Michael Hurd's lyrics are as follows:

MARY, MOTHER, COME AND SEE

'Mary, mother, come and see
Thy child is nailed on a tree.
Hand and foot he may not go,
His body is wounded, all in woe.

Thy own sweet son that thou hast born
To save mankind that was forlorn,
His head is wreathed in a thorn,
His blessed body it is to-torn.'

'Mary, mother, come and see
Thy child is nailed on a tree.'

And when this tale they came to tell,
Mary would no longer dwell
But hied her straight to the hill
Her son that she might see.

'My own dear son that art so dear
Why have they hanged thee here?
Thy head is crowned with a briar,
My lovely son where is thy cheer?'

'Mother, my leave I now must take,
My body dieth for mankind's sake,
A lonely game I now must play
For sinful souls that are to die.'

Pray we all to that blessed Son,
And bring us to bliss that is above.

Amen, Amen, Amen, in charity.
