Here's the lyrics that were sung by Bethany in that video whose link is posted above:

{I apologize for any errors in my transcription}

Sail Away, Lady

Hush little baby don't you cry
Mama's gonna love you till she die

Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock-um
Daddy

I gotta home in Tennessee
That's the place I wanna be
Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock-um

When I get my new house done
Give my old one to my son
Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock-um
Daddy

Don't you rock um
Don't you rock um
Don't you
Don't you rock
Don't you

I got ah letter from Charlotte town
Old Saint Louey is burnin done
Sail,away lady, sail away
Sail, away lady sail away
Sail, away lady sail away
But don't you rock-um
Daddy

Hush little baby, don't you cry
You'll be an angel by and by
Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock, Daddy
Don't you rock-um
Daddy

Don't you rock um
Don't you rock
Don't don't
Don't you rock um
