We consider Barney, the big purple dinosaur, to be ageless. But he's celebrating his birthday this year, and the live celebration comes to Grand Prairie's Verizon Theatre this weekend. Barney Live in Concert -- Birthday Bash! features more than 25 tunes that are designed to get kids up and dancing in the aisles. And along with the guest of honor, you'll see your favorite Barney sidekicks -- Baby Bop, BJ and Riff -- singing and dancing onstage.
