The 03/10/73 show was not scheduled initially, and added later.
Though Mr. Notoya says Jon Anderson sang "Sakura Sakura"on every YES gigs, I'm afraid it is not correct. According to a Japanese book "Live in Japan 60's to 70's", Jon sang the song at Kanda Kyoritsu Koudou on 03/10/73 (the 3rd show in Japan) for the first time. On that night, he sang it as an encore at the very end of the show.

Jon Anderson: Last night some freinds came down to see us and they sang us an old Japanese folk song and I'm going to try to sing it for you now.
