For what it's worth, this is very slightly different than what I transcribed (above) from Clary Croft's singing. I think the difference in the next to the last measure is what's important.

The words are as follows:

The Blackbird

I once knew a maiden whose fortune was so,
She courted a sailor, a young sailor boy,
She courted him dearly by night and by day
Until this young sailor he sailed miles away.

Chorus:
Then if I were a blackbird I'd whistle and sing
I would follow the ship that my true love sailed in
And on the top rigging I'd there build my nest
Like an eagle I'd fly on his lily white breast

My true love is handsome in every degree
My parents despise him because he loves me,
But let them despise him or say what they will
While there's life in my bosom I'll love the lad still.

If I was a scholar, could handle a pen,
A letter of love to my sailor I'd send
I would tell him my sorrows, my griefs and my woes
If I could but find him I would crown him with gold.

"This beautiful melody should be sung with the feeling on one beat to the bar, making the music flow with the words. It was sung for Helen Creighton by twin brothers Allister and Judson Armstrong of Sherwood, Lunenburg County, Nova Scotia, when they were sixty-five years old. When Judson's throat got tired from singing, he would eat salt to clear his voice!"

(Just so we've got one version with complete attribution!)
