We’ve seen this musical before, and it was so much fun, we began clapping and bouncing our feet with the music, something we try very hard to avoid as it makes us look like quite an idiot. It was worth it. Mamma Mia is the story of a mother, her soon-to-be-wed daughter and who the heck the bride’s father is. Bonus: the soundtrack is full of ABBA songs like “Dancing Queen” and “Knowing Me, Knowing You.” Aug 13–30, check website for times. The Music Hall at Fair Park, 909 First Ave. 214-691-7200. dallassummermusicals.org.
