My wife listens to RKK radio all the time. I like it as it is not a themed station: one never knows what the’ll toss out. Tonight, they had a delightful song, はいさよじさん, which basically means “old guy who loves festivals.” “Haya” is a celebratory exclamation. Ushibuka is famous for its festival called “Hayamatsuri”「ハイヤ祭り]. The song, linked to below, is themed on Okinawa music (沖縄音楽, Okinawa ongaku). Enjoy. - William
