Would appreciate anyone who knows this song to please check my attempt at hearing the lyrics and make corrections. Any help with the key and chord sequence appreciated also.

DRUMMER BOY
As recorded by Willie Norton on "Sierra Moon" (2006)

CHORUS: He's going off to be a drummer boy.
He's going off to be a drummer boy.
Going off to be a drummer boy,
He's fighting with the Union plan.

His brother is of a different opinion; his brother's wearing gray.
This war ain't done nothing but divide this country in hate. CHORUS

Well, they say this war's about slavery; one thing you best understand:
This war's about the federation and their Union plan.
If the Union wins this war, the land never be the same.
No matter black or white, we'll live in economic chains. CHORUS

Well, there used to be four buildings(?) on the farm; no woman(?) where I used to work.
Some were black and some were white, but we all dug in that dirt.
When the evening came around, we'd sit around the open flame,
Play a fiddle and guitar; to the good Lord we'd sing. CHORUS

Ain't no crops in the field; there ain't no crops no more,
Only tombstones growing there and that's due to this war. CHORUS

Well one thing 'bout slavery and that I understand:
Just 'cause a man is wearing chains don't make him less than a man.
Man was born poor(?), yeah; man was born to be free,
Just like he takes a stand, just like my brothers and me. CHORUS
