I fooled around with this song on a low g uke in the key of C.
It turned into kind of a chord melody thing at the beginning of the song using variations of C, then G7 and G, etc.
On a low G uke, the verse melody that starts on F can be arpeggiated.
I got it down in chord chart form, not note for note, but this might get you started.
