Theatre at the Mount opens the 2013 season with the hilarious story of friendship and revenge in the Rolodex era. “9 to 5: The Musical,” is the story of three unlikely friends who conspire to take control of their company and learn there’s nothing they can’t do — even in a man’s world. Outrageous, thought-provoking and even a little romantic, 9 to 5: The Musical is about teaming up and taking care of business…and may be the next best thing to a raise! Performances are Feb. 22, 23 and March 1 and 2 at 8p.m, and March 3 at 2 p.m. For tickets, call the box office at 978-632-2403 or online at https://mwcc.edu/tam.
