[Corvina]

She performed BRING IT ON the first time at Tokyo Girls Award Autumn/Winter 2013. Still remember it very well as we did get a really crappy fancam of it. It sounded much more electro driven in it.
Btw. it isn't a BACK-ON song. There is a short demo from them, but it's not theirs. One fan ( I guess it was maze) asked Kenji about it on social media and he answered it isn't. And even if they wrote it, they've also could have given it to Kuu. Poppin' love cocktail was written by them as well.
Also never heard Kuu saying BIO would stay live exclusive

And I seriously can't imagine Kuu releasing nothing next year. This would be strange. But with this tour theme, no new album next year and the covered up summer single this year - I really don't know, what to expect.
I just know I want studio versions of both songs!
