Apparently for the afternoon concert today, the Seishun Collection PV was shown. We can perhaps hope someone would have recorded it, but eh, it's a little difficult to do that with people patrolling the aisles.
Recording the sound is one thing, video taking might be a tad more challenging.
Reading comments on 2ch. Some commented the PV had a "refreshing" image. Apparently there
are outdoor scenes where they filmed at a soccer field? There are also trampolines involved where they jump around on. Also they have parts where the girls hold up handwritten messages on boards. Hmm. Sounds promising. Maybe. Haha. I'm pessimistic when it comes to expecting good videos.
