Walnut Street Theatre, located at 825 Walnut Street, is producing the Tony Award winning musical How To Succeed In Business Without Really Trying on its mainstage through July 13th. With its 20 musical numbers, many accompanied by dance routines, the audience does not need the applause sign which appears briefly, because applause continues non-stop throughout the production. Jeremy Morse, portraying J. Pierrepont Finch, window washer seeking a career up the corporate ladder, is only one of the many talented cast members. Becky Gulsvig, portraying his love interest Rosemary Pilkington, has a very strong voice. But watch out for Joliet F. Harris, playing J.B. Biggley’s secretary, Miss Jones. Her moves and the way she can belt out a song will have you rockin’ in your seat. Mark Jacoby, playing J.B. Biggley, the president of the corporation, not only has a wonderful stage presence, but a mellow baritone to match it Thanks to the creative choreography of Michele Lynch, and a very talented ensemble, the dancing routines of both the men and the women bring the house down. Outstanding set designs are not uncommon for Walnut Street’s mainstage but scenic designer Robert Andrew Kovach had his work cut out for him with the many scenic changes required for this show, including several with an elevator. All are beautifully executed with a two-story stage. Everyone who has played a part in this extravaganza is to be congratulated for an effort exceptionally well done. Come out and join in the fun.
