I can't find it on any of the Ashley recordings that I have. It is not on the Watson and Ashley set of 'Old Time Music at Clarence Ashley's'. I have a version by Jody Stecher and Kate Brislin as a delightful banjo duet. Their source was Oscar Wright but, as they say, sounds like 'Roscoe Holcomb meets Hank Bradley'.

ELKHORN RIDGE

Standing on top of old Elkhorn Ridge
My true lover by my side
Waitin' for some east bound train
Lookin' for to take a ride

Yonder stands my own true
(S)he's all dressed in brown
(S)he is the darlin' of my heart
I'll see him/her when the sun goes down

Working on your county road
For a dollar and a dime
Give a dollar to that gal of mine
This old dime is mine

Crazy, crazy, crazy, crazy
Darlin' I'm crazy about you

Standing on top of old Elkhorn Ridge
My true lover by my side
Waitin' for some east bound train
I'm lookin' for to take a ride

I hope this is of some use to you.
