The music video showcases “Rere no Aoi Sora,” performed by Japanese stringed musician Kiyoshi Kobayashi under the pseudonym “Ukulele Ojisan.” It was featured on NHK’s Minna no Uta program, and the same month it was released as the title track on a two‑disc CD produced by Nippon Columbia, which also included a selection of other songs from the Minna no Uta catalog.
