Update:
Apparently Charles E King's "Ne Lei O Hawai'i" IS the same "Song Of The Islands" that I sing (though I'd still like to hear it in Hawai'ian to see how the words fit).
When I heard a recording of a song bearing that title that was a different tune, I figured it wasn't the song I was looking for, so I didn't check out other recordings of "Ne Lei O Hawaii" on YouTube. But after reading your last post, Q, I did just that, and, yes, the other ones I checked are the same tune.

I do know that there is at least one other "Hawai'ian" song, with a different tune, called "Song Of The Islands." I've seen the sheet music for it, a while back. Not at all the same song. But at least one mystery is solved - I know that Charles E King wrote the music for the "Song Of The Islands" that I sing.

Thanks, Q.
