They're not the "Jonas Brothers" tho, They are going on tour just to answer a few questions and that's all. They're not doing music and they call themselves Joe & Kevin Jonas, not Jonas Brothers. so no.
PS: They are not planning on working on music either. It's just this interactive tour and that's all. Joe is working on his solo project and Kevin has a tv show coming out soon.
Right? Not sure what they're gonna do without the only one in their group who can write, play, sing and perform, but okay. Good luck to them I guess. Nick and his infinite talent remains unbothered.
