Here are the lyrics from The Joan Baez Songbook (1964, Ryerson Music Publishers, New York - a division of Vanguard Records). It's just a bit different from the version in the DT.

COPPER KETTLE
(Frank Beddoe)

Get you a copper kettle.
Get you a copper coil,
Cover with new-made cornmash
And nevermore you'll toil.

CHORUS
You'll just lay there by the juniper
While the moon is bright,
Watch them jugs a-fillin'
In the pale moonlight.

My daddy, he made whiskey,
My granddaddy did too.
We ain't paid no whiskey tax
Since seventeen ninety two.
We just lay there....

Build you a fire with hickory,
Hickory, ash, and oak.
Don't use no green or rotten wood,
They'll get you by the smoke.
While you lay there....

Get you a copper kettle.
Get you a copper coil,
Cover with new-made cornmash
And nevermore you'll toil.
You'll just lay there....
