Exclamation points aside, there is little to recommend in this 1966 musical—depicting the life span of a fifty-year marriage—from Harvey Schmidt and Tom Jones (the creative team behind “The Fantasticks”). The current American Theater Company revival—updated and shifted to a Chicago setting by director Michael Weber—features the incomparable Heidi Kettenring (recently seen wheeling around as Nessarose in the Chicago production of “Wicked”) and a very solid Stef Tovar as a pair of middle-class normals raising kids and the rest. The musical is a two-hander, accompanied here by twin pianos. As a study in marriage, the show is cloying and precious—the highs too sticky sweet; the lows too obvious and broad. I enjoyed this material about as much as the generic claptrap in “I Love You, You’re Perfect, Now Change.” But if you are a fan of wigs, this is your show—Kettenring sports the gamut, from a bouffant, to a Dorothy Hamill, to a confection worthy of a guest appearance on “Dynasty.” (Nina Metz)
