Families with children should make their way to the Bristol Riverside Theatre where the company is staging The Drowsy Chaperone, Jr. (August 1-7). The innovative musical concerns a devoted musical theater fan whose favorite cast album suddenly springs to life in his living room and tells the tale of a Broadway starlet in search of true love. Next, is Nickelodeon's Blue's Clues Live! Blue's Birthday Party (August 8-14), an interactive show that encourages the audience to join along as Blue celebrates her birthday with pals Tickety Tock, Slippery Slope, and Periwinkle.
