It's on the Folkways album, Old Time Music at Clarence Ashleys. I'll look it up tonight and give more info tomorrow. What I remember is

I'm as free little bird as I can be
I'm as free little bird as I can be
I'm as free at my age as a bird in a cage
I'm as free little bird as I can be

Carry me home little birdy, carry me home (lns 1,2,4)
Carry me home to my wife, she's the joy of my life (ln 3)

I'll never build my nest on the ground
Neither in the forks of a tree
I'll build my nest in the ruffles of her dress
Where the bad boys can never bother me
