An unpublished song by legendary singer Hibari Misora has reportedly been discovered, and it will be released to the public later this month. Titled "Au wa Wakare no," the song is said to resemble her 1966 hit "Kanashii Sake." It was composed by Yoshiyuki Kozu, with lyrics written by his wife, actress Meiko Nakamura. During her lifetime, Misora was good friends with the couple and she created 11 songs with them, though this was the only one to never be publicly released.

The song was apparently found just this month. In April, the Hibari Misora museum was reopened, and as a related project, all of her songs were cataloged to create a "customized CD" system, which let fans create their own album composed of their 20 favorites songs from her 559 singles. Earlier this month, 120 songs taken from her albums were added to that list, and in the process, Columbia Records found the recording of "Au wa Wakare no."

The song will be heard by the public for the first time on Saturday during an evening special on TV Asahi. It will then be made available only through the "customized CD" system, starting on October 1.
