I also liked the episode. It's an enjoyable romp into the past for those who were in "The Greatest Generation." For the rest of us, "Boomers and Beyonds" the time- travel-esque quality was very engaging. I rate this cleverly written, and terrifically sequenced show a 5.  The reason for the high score comes because those in Hy Brown's post-production crew added great period elements, spectacular music choices, in particular.
By the by, if anyone can conjure up the name of the tune with the Sax Quintet just as the officer is meeting the "Boss" at Morrisey's initially, I would pay money to know the name of the tune.  Please post that, or a list of the entire score if anyone's got the discography knack.
Thanks in advance for the big band guru.
