I know some snippets of this song--

Bonny May a shepherdess has gone
To call her sheep from the fold,
And as she sang her bonny voice it rang,
Right over the tops of the downs, downs,
Right over the tops of the downs.

There came a troop of gentlemen
As they were riding by.
One of them has lighted down
And asked of her the way, way,
And has asked of her the way.

He's taken her by the middle gimp
And by the green gown sleeve,
And he has had his will of her,
And he's asked of her no leave.
He's asked of her no leave.

The fox has come to the fold door
With twinkling eye so bold,
And ere he'd take the lamb that he did,
I wish he'd taken them all.
I wish he'd taken them all.

ONE OF THE LATER VERSES IS...

You lie. You lie, you Bonny Bonny May.
So loud I hear you lie.
Remember the misty murky night
I lay in the fold with thee, thee,
I lay in the fold with thee.
