Is this it? The tune is there, as well.
Willie the Waterboy

1. As young Mary lay sleeping, young Willy came creeping
To her bedchamber door did go,
Saying 'Arise and awake, young lovely Mary,
For I am your true love, young William O'

2. Then young Mary arose and put on her clothing,
Straight to her bedchamber door did go,
And there she spied her true young William,
Whom she'd not seen for some time ago.

3. "Seven long years I've been daily writing
All over the Bay of Biscay O
But cruel death sent me no answer,
Sent me no answer from my William O."

4. "Then it's Willy dear, hide o'er those blushes,
Those blushes you wore being long ago?"
"Then Mary dear, the cold clay has worn them,
For I am but the ghost of your William O."

5. "If I had all the gold that was in the West Indies,
Or all that was in King George's throne,
I would freely give it to the Queen of England,
If she would grant it to me my William O."

6. They spent that night in deep discussion
Concerning their courtship being long ago.
They kissed and shook hands with a sorrowful parting,
Just as the cock was a-going to crow.
