Despite the original Broadway production’s less-than-lukewarm reception from big-city theater critics, the national touring production of “9 to 5” is an amusing mélange of feel-good music, memorable characters and campy ’70s nostalgia. Based on the 1980 cult movie starring Lily Tomlin, Dolly Parton and Jane Fonda, the musical comedy follows three office gal pals who conspire to hold their chauvinistic boss hostage in order to shatter the company’s glass ceiling and boost company morale. Dee Hoty, Diana DeGarmo and Mamie Parris have been well cast in the lead roles of Violet Newstead, Doralee Rhodes and Judy Bernly.
