There has recently been some discussion of the song "Sitting on Top of the World". Brian Hoskins has given the lyrics for the (possibly original recorded) version by the Missippi Sheiks..JonW supplied lyrics for the Charlie Patton version called Some Summer Day.
There is a version by Doc Watson in the DT also called "Sitting on Top of the World".
I was just listening to some Robert Johnson songs and lo and behold there was the same melody in his "Come into my Kitchen".
I would be curious to know of other versions both new and old.
The other song that has been intruding on my consciousness lately is "Spoonfull." Charlie Patton and Mance Lipscomb both have a version by that name (same tune but very different styles of playing.) Mississippi John Hurt has a version called "Coffee Blues". I am told some modern groups have done it. Again I would be interested in other versions, old and new.
