Dang! I spent half an hour transcribing this thing because some of the words are hard to understand - and now I see that Stewie found lyrics in a CD booklet. This is a later recording, and the wording is a little bit different. Since my transcription is by ear and Stewie's from the CD booklet, I'd say Stewie's is the definitive transcription. Nonetheless, I'll post mine so you can see the slight differences between the two recordings.

PRETTY BIRD
(Hazel Dickens)

Fly away, little pretty bird,
Fly, fly away
Fly away, little pretty bird,
And pretty you'll always stay.

I see in your eyes a promise
Your own tender love you'll bring,
But fly away, little pretty bird,
Cold runneth the spring

Love's own tender flames warms this meeting
And love's tender song should sing
But fly away, little pretty bird,
And pretty you'll always stay.

I cannot make you no promise
For love is such a delicate thing,
Fly away, little pretty bird,
For he, he'd only clip your wings.

Fly, fly away, little pretty bird,
Fly, fly away
Fly away, little pretty bird,
And pretty you'll always stay.

Fly far beyond the dark mountain,
To where you'll be free evermore
Fly away, little pretty bird,
Where the cold winter winds don't blow.



from the 1987 Rounder CD, A Few Old Memories
An earlier version was recorded for the Rounder album, Hazel and Alice
