"Sittin' On Top Of The World", as Walter Vinson of the Mississippi Shiks told me, was written by him---the man himself---Walter Vinson. He allowed me to tape record a jam between himself and Buffalo Bill Lucas and Bill Pierson in Chicago (about 1962) at the home of Bill Pierson on South Michigan Avenue. As the day drew on, and Walter drank more and more, he got more and more pissed off about that song. He saw very little, if any, cash from his song. Many others recorded it and copywrote it (or their arrangement of it)--including bluegrassers.
