(Cherry could also be a member of the band ([this](https://derpibooru.org/images/3153390?q=g5) is the image with those tags), though I'm not sure. The synopsis for one of the stories mentioned the lead singer losing their voice; given [this panel](https://derpibooru.org/images/3153380?q=g5), Cherry is probably that lead singer.)
