@Grivusangel -- I didn't hear much of "America" in it, either. I'll have to find the hymn you mentioned and give it a listen.
Most Hawaiian music is just beautiful, and their culture is so diverse. It's great for the country as a whole that they have kept so much of their native culture and so many of their traditions alive. We need to remember we come from a variety of backgrounds and beliefs and need to respect all of these.
I'd love to visit Hawaii and hear this beautiful song live some day. That would be a treat.
