"Angel Band" was recorded by the Carters between 1952-1956. A nice recording, the Acme sessions.

"Are You Tired of Me, Darling" - words G.P. Cook, music Ralph Roland, 1877. Sheet music at American Memory. Fred Kenyon Cook set it to his own tune in 1878; dunno which one the Carters used, although websites indicate the former.

"Bearcreek Blues" - These verses occur in a number of old songs. First two verses are in 19th c. collections. The Carters seem to have made up the verse about Jesse James.

"Beautiful Home" - Shares ideas with "Beautiful," a hymn by Barney E. Warren, 1897, "Beautiful Home," Warren 1911, and "I Have a Home," 1897, also Warren. Not the same. Hank Williams Sr. sang the lyrics used by the Carters.
Another hymn, "Beautiful Home," by A. E. Bloom, pub. in Golden Sheath, 1902, is not the Carter song.
Not found.

"Beautiful Brown Eyes" - Copyright by Arthur Smith and Alton Delmore. Removed from Randolph "Ozark Folk-Songs," Revised Edition, because of this. See thread 6744: Beautiful Brown eyes
Some lines used in older songs.
