During the programme, AKB48 reminisced on the groups history, including their first Music Station appearance to promote 'Skirt, Hirari' in 2006. They also performed a single medley of 'Flying Get', 'Ponytail to Shushu' and new song 'Yume no Kawa'. 'Yume no Kawa' will be Acchan's last song with the group, and the members were so overwhelmed they couldn't control their tears, with Acchan breaking down and crying during the performance.
