As the title implies, the record concentrates on up-tempo swingers. Again, the songs were all standards -- "Just One of Those Things," "Wrap Your Troubles In Dreams," "All of Me" -- that benefitted from the new thematic setting, the new arrangements, and, of course, Sinatra's increasingly playful and textured vocals. Sinatra plays around with the melodies without leaving them behind, delivering each line with precision. It ranks as one of his most jazzy performances, as well as one of his most fun and carefree records.
