When Susie is playing cards with soldiers in the bunk room, the soldier in the white tank top has a cigarette over his left ear in a close up scene, but not in any of the other parts of that scene.
In Season 1:4, Midge and Susie are in the record store when Midge says, "Never watching 'White Christmas' again." Then in Season 3:1, she claims to be unfamiliar with "White Christmas".
In this episode set in 1959, the USO Band starts playing the Phil Spector arrangement of "White Christmas", which didn't come out until 1963.
In the opening sequence, it would appear that the USO performance takes place on an active US Air Force base; however, the aircraft are an odd anachronistic assortment for 1959.
The P-51 Mustang in the background has markings dating from World War II. It wears the US Army Air Force blue and white "star and bar" insignia used from late 1943 to 1947. In 1947, a horizontal red stripe was added to the bars on either side of the star in the national insignia. The red tail identifies the 332d Fighter Group of World War II, and the yellow trim tab identifies the squadron within the group.
Another aircraft in the background, glimpsed several times, is a B-25 Mitchell, a World War II type long retired from active service by 1959. A C-47 in World War II olive drab and neutral gray coloring also appears in the background. This assortment would only make sense in an air museum.
The jet seen in the background is an F-84, which was flown in the 1950s, though few of its type were still in service by 1959.
