Lighter,

so...Is there a musical notation in E&S? If not (i.e. no tunes to compare) I'd be stumped for how Colcord may have made a connection to "Cherokee"

I'm not so sure about "grand chorus"-- at least in how I use term, neither Cherokee of Kanaka has one. They do both have that extra (3rd) solo -- the way hey / yodel one, i.e.

Cherokee: Hauley high and a hauely low (Hugill) / Way hey ya (Colcord)
Kanaka: Tu lai aye o tu lai

(The modern versions of "Cherokee" have turned this into a grand chorus of sorts, with everyone singing along on "Way hey ya". Incidentally, this creates the type of "error" noted by Greg B up-thread (and heard clearly in Geoff Kaufmann's live recording) whereby an audience, assuming a 4th phrase, belts out the line.)

Anyway, I'm most surprised that the E&S version doesnt include a yodel/way-hey solo.
