E.C.Ball recorded Warfare on a County recording in 1967. I have it on a reissue/compilation on Copper Creek CCCD-0141, E.C.Ball and Orna, "Through The Years 1937-1975". I'm not familiar with a Carter Family version, but in the liner notes it says that E.C. met the Carter Family when he was about twelve or thirteen years old..."Most any of the Carter Family songs were kindly up my alley. I liked 'em."

I also see that John Cohen recorded E.C. (Estil) Ball and included Warfare on Rounder CD 0028 High Atmosphere.

From the notes of High Atmosphere:

"In this church song, we see the problem posed by the chorded guitar as applied to the older modes of music. The guitar acts as a leveling force against the modal inclinations of this music, trying to smooth out its rough edges and craggy peaks. No wonder so few of the ballads are accompanied in any but a linear fashion. Yet Estil Ball's beautiful singing makes a charming reconciliation between these conflicting forces, while his guitar chords shift from major to minor to find a fitting accompaniment. Sarah Ogan Gunning and Wade Mainer have also recorded this song."
