That Jimmie's right purty too, it seems. (Referencing a photo in his bio in the link above.)

I wonder if the yodel was his approximation of the appoggiatura, portamento, and embellishment of pure melody on melody he'd heard from black singing co-workers-- spirituals, etc., coming out of the African vocalization style.

I kin 'bout hear it now. Jimmie says, "SWISS??? Man, I dunno SWISS, whatchoo tawkinnabout?"

I really don't know. I am sure someone who DOES know will wander in soon! Hope so anyway!
