The title track was an era-defining description of how the sexual revolution was actually started by confused, recently divorced parents instead of their hippie offspring. Sinatra actually tired of the tune quickly, so he grabbed arranger Nelson Riddle and built a quality album around the hit. Here, Riddle and Sinatra are in Count Basie mode, with a jazzy organ fronting a sleek big band. The brilliant "Summer Wind" and "All or Nothing At All" are heralded classics, though the wondrous "On a Clear Day" may be the single most underrated tune in the entire Sinatra songbook. The expanded edition adds two surprisingly strong concert cuts from 1985 and an alternate studio reading of "Yes Sir, That's My Baby."
