Twist and Shout

It's like a dream come true! This week's Mystery Guest at Camp Rock n' Roll is Ashley's all-time favorite group, 4You! 4You will be choosing campers to mentor for the end-of-the-summer showcase. Ashley wants to be chosen -- but so does Madison, the lead singer in the rival band. Can Ashley find a way to sing with the most popular group in the world? Mary-Kate loves jamming with her band -- they've all become great friends, and her new boyfriend is even part of the group. Then a record industry executive stops by camp and tells Mary-Kate that she has real talent -- but her band is not as good as she is. He tells her to find a new band before he comes back for the showcase and he can make her a star. Will Mary-Kate dump her friends for the promise of fame?
