In the Shadow of Clinch Mountain was recorded in NYC in 1937. According to the Carters biography Sara sang the song to Jeanette, whether it's Sara's song or A.P.'s song and if it's based on another song I don't know. It seems like it could be a Carter original.

Anyone?

IN THE SHADOW OF CLINCH MOUNTAIN- Carter Family

Oh, I grew up on the side of Clinch Mountain
'Mid the beauty and the wonders of the woods
Where sweet songs from the bright, sunny fountain
And the warbles of the birds I understood

Then I asked how this green, lofty mountain
In the cavern of the lonely desert stood
Said the songs of the bright, sunny fountain
We are given by the waters of His love

    When I've sung my last song in the evening
    And the sun sets in the golden west
    All the scenes of this world I'll be leaving
    In the shadow of Clinch Mountain I will rest

    [INSTRUMENTAL BREAK]

Through the gates I have passed now from childhood
O'er the railways to the valley of the west
Singing songs of the Clinch Mountain wildwood
Songs neighbors sang and birds still sang the best

    When I've sung my last song in the evening
    And the sun sets in the golden west
    All the scenes of this world I'll be leaving
    In the shadow of Clinch Mountain I will rest
    [INSTRUMENTAL BREAK]

Long ago stood the oaks and the cedars
Singing sweetly in a whisper of the past
Stand they not now, those great towering leaders
Nor the fountain where their crystal gleams are cast

    When I've sung my last song in the evening
    And the sun sets in the golden west
    All the scenes of this world I'll be leaving
    In the shadow of Clinch Mountain I will rest
