Not surprisingly, love is the subject of Chester Playhouse's summer theatre confection Heart to Heart. The hook is that it's not one story, but five short vignettes exploring various permutations of "mature" love. It stars Canadian theatre greats Lally Cadeau and Nigel Bennett, who are clearly enjoying both the play and each other as they change costumes, accents and hairstyles at a dizzying speed. The vignettes include a man and woman meeting each other for the first time through a singles ad, an efficient secretary who's hopelessly in love with her gay boss, a husband and wife, both actors, facing aging and mortality, a disturbingly truthful brother shoring up his sister on her wedding day and a couple attempting to broker an agreeable divorce as they vacation together. It's a light romantic comedy with a twist, and with two wonderful actors who manage to make it memorable.
