island folklore gathering

This one‘s kind of niche but I‘m sure I‘ll be successful in my search here!

Hey y‘all, I‘ll be working on Iriomote for 2 months this summer and I‘m currently on a special mission to learn folklore karaoke songs so I‘ll make lots of 地元の友達 🤠 I am looking for anything well-known in Okinawa, especially the Taketomi-Area. My list of songs I can SING (I absolutely cannot sing 僕ら東京さ行くだ because it‘s way too hard) so far consists of:

島んちゅの宝-BEGIN (THE classic)

なだそうそう-リミ夏川 (my personal favorite)

十九の春 – I need help with the Interpret here because I remember a version where a male and female sings. Any ideas which one it was? I need to surprise おじさん.

木綿のハンカチーフ-従日稲垣 (super good vibes)

銀の龍の背に乗って-中島みゆき (Dr. Cotos Clinic, iykyk)

some classics everyone in Japan knows like:

真夜中のドア-三木松原

悲しみが止まらない – ANRI

bla bla, the list goes on. But the vibe is like older island people because I know enough for the younger generation. For example, おじさん told me that literally nobody does not know 十九の春 but I also literally cannot find anything comparable on the internet because it‘s lowkey too niche.

Any advice and songs recommendations are super appreciated and will be learnt and sung! If you have any idea if there‘s another subreddit where I could find better info, drop it too! よろしくお願いします and あけおめ！😙
