Try this -
Here I sit on Buttermilk Hill,
Who could blame me cry me fill?
And every tear would turn a mill;
Johnny has gone for a soldier.
CHORUS: Shool, shool, shool a-roo,
Shool a-sac-a-rac-ca bib-ba-lib-ba-boo.
If I should die for Sally Bobolink
Come bib-ba-lib-ba-boo so rare-o.
I'd sell my clock, I'd sell my reel,
Likewise I'd sell my spinning wheel
To buy my love a sword of steel;
Johnny has gone for a soldier. CHORUS
Oh my baby, oh my love,
Gone the rainbow, gone the dove.
Your father was my one, true love;
Johnny has gone for a soldier. CHORUS
I got it from a Revolutionary history web site, so I think it's a pretty authentic version
