Here are couple of other little bird songs. Nothing to do with that one, but I like it when you get songs echoing each other, especially when they come from completely different places and times.

Little birdie, little birdie
   Come and sing me you song
   Got a short time to stay here
   And a long time to be gone

There are verses that go with this, but I've never heard any that match up to it - but it goes well added on to Will the Circle be Unbroken.

And here's the other, recorded y Doc Watson with these words:

Free Little Bird

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

Carry me home little birdie carry me home
Carry me home little birdie carry me home
Carry me home to my wife she's the joy of my life
Carry me home little birdie carry me home

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