I listened to this famous enka song called "Yume wa yoru hiraku" (夢は夜ひらく), "The dream opens at night", performed by also famous folk singer Kan Mikami and not yet famous Okinawa Electric Girl Saya.
This version is a combination of the lyrics of the hit version by Keiko Fuji and the lyrics Mikami wrote for his version in 1972, which was banned for its negative portrayal of Modern Japanese Culture.
