"Aloha Oe", Hapa Haole's Greatest Hit?

I found This while looking for some info about the writing of "Aloha Oe."

Source: Jonathan Wong - This song of farewell between two lovers is the most famous of the Queen's compositions, written in 1878. The tune of the verse resembles "The Rock Beside the Sea", composed by Charles Crozat Converse and published in Philadephia, 1857. The melody of the chorus is remarkably close to the chorus of George Frederick Root's composition, "There's Music In The Air", published in 1854. There is a manuscript of "Aloha Oe" in Queen Lili'uokalani's handwriting in the Bishop Museum. Lahilahi Webb and Virginia Dominis Koch tell of a visit by the queen and her attendants to Maunawili Ranch, the home of Edwin Boyd on windward Oahu. As they started their return trip to Honolulu on horseback up the steep Pali trail, the queen turned to admire the view of Kaneohe Bay. She witnessed a particularly affectionate farewell between Colonel James Boyd of her party and a lovely young girl from Maunawili. As they rode up the steep cliff and into the swirling winds, she started to hum this melody weaving words into a romantic song. At the top of the pali, a cloud hung over the mountain peak and slowly floated down Nuuanu Valley. The queen continued to hum and completed her song as they rode the winding trail down the valley back to Honolulu. Translation by Liliuokalani

Isn't Hapa Haole defined musically as a song with Western or mixed Hawaiian melody with Hawaiian or mixed Hawaiian/English lyrics? By this definition "Aloha Oe" pushes the history of Hapa Haole music well back before the 1903 date of "My Waikiki Mermaid" being written. This is no disrespect towards the Royal author of what's arguably the National song of Hawaii, but is a confirmation of the legitimacy of a style of music often left to Tin-Pan Alley hacks.
