There are also some notes on the web, by John Fahey which contain the following information.

3. "Spanish Fandango" by Bill Boyd and his Cowboy Ramblers, 1938 (sweetened' pop version of (1)
4. "Spanish Fandango" by Mississippi John Hurt, 1966. Arguably a distinct, unrelated piece, just to confuse us all.
