The last single released by YUI, “fight”, was selected to be the theme song for Sapporo Beer’s Hakone Relay Race.
The commercial can be seen here:
At the end of the commercial you can hear a full choir singing the chorus along with YUI.
Even thought YUI performed with a choir of young students on TV, and some people expected this version to be included in the single CD, this version of the song was unheard until now.
I wonder if Sony has other rare unpublished songs hiden in its dark vault?
