''Cheap thrills can get pretty old,'' sings Sir Elton in one of many balm-cream ballads that revel in contentment, sobriety, and new-found love. His voice and ability to craft canny hooks remain intact. But some cheap thrills, like crass rock & roll, shouldn't be abandoned, and Peachtree Road's few attempts to rock out are tame and hokey. Even when he's not writing for family fare soundtracks or musicals, he still sounds like he is.
