There is a recording of Charlotte Higgins singing "I Must Away" - perhaps more common known as "Night Visiting Song" - at www.tobarandualchais.co.uk. It was recorded in 1955 by Maurice Fleming. I have been trying to make out the words, and I wonder if anyone would be prepared to listen and suggest any changes to what I've got so far?

I MUST AWAY
sung by Charlotte Higgins

1. I must away, I can stay no longer;
This morning's tempest I have to see.
And over the high hills I rove with [lightness?]
Until my arms I love [have?] my dear.

2. And when he did come to his true love's window,
He kneeled it low down upon a stone;
And through the window, he whispered slowly,
It's my true love alone within?

3. She lifted her head off yon soft down pillow,
And thrown her arms roond he lily-white breast;
And through the window she whispered slowly,
How's thee disturbing me of my night's rest?

4. O rise, o rise, it's your own true lover,
O rise and open, and let me in.
For I am wet, love, besides I'm weary,
I am wet, love, unto the skin.

5. Up she had got with the greatest of plaisure,
She opened the door and she let him in;
So they both claspit into each other's arms,
Till the slow night was fast and gone.

6. But when this long night was fast and over,
And all the small birds began to crow,
So they both shook hands and they kissed in [parting?]
He sounded his bugle and away did go.
