Oliver! -- The songs are still the heroes in Cain Park's production of Lionel Bart's Oliver!, but even with a compelling tale and great music, this open-air production seems less than a sum of its parts, thanks to lapses in the pacing and book scenes that slog rather than snap. Oliver!, adapted from Charles Dickens' novel about poor orphan Oliver Twist, starts off in a horrific workhouse and moves through all strata of British society -- from scoundrel Fagin's grimy den of pickpockets to the gracious Brownlow's cushy crib -- giving us a walking tour of degradation, survival, and finally, hope. Fagin is abetted in his nefarious activities by Nancy (Patty Lohr), a gutter rat who is in a doomed relationship with the vicious robber Bill Sykes (a snarly Bob Russell). As Oliver, young Lincoln Sandham is appropriately thin, physically and vocally, but more could be made of his feisty side. George Roth, as Fagin, captures the right blend of mendacity and avuncular paternalism, and Patty Lohr makes a strong-voiced Nancy. But in a cast numbering almost 55, the real standout performers are the workhouse boys and girls, along with Fagin's motley crew, who are all consistently focused, disciplined, and energetic on stage. Credit their mature presence to director Fred Sternfeld and the gifted Martin Cespedes, who choreographed and staged musical numbers. Sternfeld, however -- usually masterful at managing large-cast shows -- seems to lose his firm grip on character and pacing in several scenes. The dysfunctional Mr. Bumble (Kris Hebble) and Widow Corney (Juliet Regnier) seem more corny than comical, and when the kids are asleep in the thieves' kitchen, Fagin wanders from his table to the fireplace, seemingly without purpose, until the audience begins to nod off too. This Oliver! just barely earns its exclamation point, thanks largely to the kid singers and dancers who repeatedly kick it back to life. Through July 8 at Cain Park, corner of Lee and Superior roads, Cleveland Heights, 216-371-3000. -- Howey
