Hi Jerry, Lonnie D recorded 'Ole Riley' before he went solo, I had it on an EP which also included Dickie Bishop singing 'Gypsy Davy'.
Ramblin' Jack Elliott recorded 'Here Rattler' on an EP called 'Kid's Stuff', As I recall his first verse went :-
Rattler was a fine ole dog, fine as he could be,
He'd tree a 'possum in a holler log and never let him be.
