AllMusic's Stephen Thomas Erlewine wrote: "Standing in contrast to the moody 2015 set No One Ever Tells You, 2017's In Full Swing contains some of the sunny brio its title suggests.

As always, MacFarlane and McNeely are so besotted with Frank Sinatra's classic long-players for Capitol that their act can seem like a bit of swinging cosplay, with MacFarlane mimicking Old Blue Eyes' finger-snapping charm and McNeely penning love letters to Nelson Riddle, but their execution is expert and, since the touch is light, In Full Swing feels looser and better than its predecessors.

Alongside top-tier standards from the Gershwins, Irving Berlin, Jerome Kern, Rodgers and Hart, Lerner and Loewe and Jimmy Van Heusen, he unearths several less precious though no less glittering baubles.

Among them: the overjoyed "I Like Myself", from It's Always Fair Weather; the jaunty Gordon MacRae-Gisele McKenzie number "My Buick, My Love and I" (featuring Elizabeth Gillies); the pert "A Kiss or Two"; and a sparkling parry with Norah Jones on "If I Had a Talking Picture of You".

Through it all, you can't help but be carried away by MacFarlane’s joie de vivre, like a kid in a candy store gleefully sharing his sugar-dusted treats.
