^ This is what i thought too, that it was an old video.
But she made a post on TA with a pic of rehearsal with the band and she has short hair just like in the video, plus she mentions in the post that the Korean back singer will be there on the 31st show just like the whole band and you can see her in the vid so nope, it seems the video is indeed recent
Speaking about TA i'm really mad that they stopped translating her posts in english, all they keep saying is that the translation will be up soon but the last time they translated one was like in september?! --
Yeah the fact that they kept this outfit surprised me too! Maybe they do keep all of them...
