Willy, I've been to loads of islands, never really saw anything that looked that great except at some of the resorts. Unfortunately, most of the stuff we hear and see is generated out of Hollywood, which is not remotely close to being the real thing. But it sure made Hollywood a lot of money.
As a retired singer/musician/entertainer, I like many in this field, have to perform a wide variety of music for my clientele, often for a specific party theme. When the folks that hire me tell me that they are having a Luau I usually end up playing a lot of old songs by Don Ho, who worked right up until the day he died at 96. Don lived and worked in Hawaii much of his life, but ironically, the vast majority of the songs he performed were written in the US. Usually, at the Luaus, after a half dozen songs like Tiny Bubbles, they will request some Jimmy Buffett and Zach Brown songs, which I would much rather perform. I also usually threw in song Harry Belefonte songs, which were always about the Caribbean islands.
The Pirates Of The Caribbean music from the music is neat, but it really does not reflect the music native to the islanders, which is mostly slow to intermediate drumming with a few whistles. Yes, they did have some dancing ladies back then, but nothing like the ones portrayed in the above video. But, keep those dreams alive my friend - dreams are what keeps us going.
