I don't know why I did not think of this before, I even have the sheet music for it bookmarked. Go to the Levy site, enter Keemo Kimo in the search box.
This should return five documents, with two broken. There is a Keemo Kimo Schottisch composed by James Bellak, 1854, and a version arranged for the cotillion, but the one you want is entitled Keemo, Kimo! The Celebrated Banjo Song, Arranged for the Piano Forte. This version includes the words.
