From W.C. Handy, ed., Blues: An Anthology (1926, 1949; Macmillan, 1972, p. 207):

This ["Memphis Blues"] is the first (1912) published version of this first written blues, interlined with some of the many frivolous or traditional verses that were sung to its tune in the 1909 campaign. The entire first strain of the music was omitted in Bennett's vocal edition of 1913.
