Stecher and Brislin say in the notes to 'A Song that will linger' that their arrangement 'owes more to the Stanley Brothers than the Carter Family who first popularised it'. Their version has only 3 verses, more or less as you posted them.

The Stanleys recorded it for Ray Davis' Wango records in the early 1960s and the recording was reissued on County 754 'Stanley Bros of Virginia vol 4' in 1976 (County reissued 4 Wango LPs). Their version has only 2 verses - the 'roses nod' one and a second where the 'little boy' is 'a little girl':

On a cold, dark Sunday morning
In a country far away
A little girl from old Kentucky
Lifted up her voice to sing

It seems that Stecher and Brislin used 2 Carter Family verses and one that was similar to the Stanleys' second verse. I do not have any recording of it by the Blue Sky Boys so I do not know what they sang.
