Both goofy and sexy, shruggingly insouciant and rigorously polished, Ms. Foster's performance embodies the essence of escapist entertainment in the 1930s, when hard times called for bold smiles, tough wisecracks and defiant fantasies of over-the-top opulence...Her pleasure in her material creates a sheen that illuminates everyone around her. Mr. Donnell, Mr. Grey and Mr. Godley are never better than in their duets with Ms. Foster, energetic competitions in putting over some of Porter's cleverest lyrics.
