Yo Gabba Gabba! is a children's television show on Nickelodeon co-created by Christian Jacobs, who's better known in punk circles as MC Bat Commander of the Aquabats. YGG! is coming to town at the Fabulous Fox on March 21, as we reported a few weeks ago. Just yesterday, the Aquabats announced a March 21 show at the Firebird. What are the odds? Especially since my sources say that this is a total coincidence. I'm guessing, however, that the 'Bird show is going to be a total party, because the Gabba crew's going to be in town. Get tickets early; they go on sale Friday at 5 p.m.
