Music critic Stephen Thomas Erlewine, in his review of the album for Allmusic, awarded it two-and-a-half out of five stars, and described it as, "More of a singles collection than a proper album [...] Much of this has a rock-oriented pop production, complete with fuzz guitars, reverb, folky acoustic guitars, wailing harmonicas, drum kits, organs, and brass and string charts that punctuate the songs rather than provide the driving force [...] the songs Sinatra tackles with a variety of arrangers are more ambitious than most middle-of-the-road, adult-oriented soft rock of the late '60s."^[1] Erlewine described the album's ninth track, "Drinking Again", as "exceptional, nuanced" and said that it "ranks among the best songs Sinatra cut during the '60s."^[1]
