Im sure that it hasnt, since after the single release the group stopped acctivity, and its only the recent years that YK and Chiaki started performing/covering their See-Saw songs again
I hope that performance gets recorded. I'm also diying to listen to Seijaku wa Headphone no Naka live
^ We dont add performances of other artists in non-kajiura/Kalafina events or we would have to add thousands of more setlists just for 2-3 songs on each.
