An anomaly in that scene: Though FFC was absolutely, fanatically meticulous about getting period details right, note that a guy standing behind Moe is wearing a "formal turtleneck" shirt. That style--wearing a turtleneck with a sports jacket instead of a shirt and tie--didn't come in until the mid to late Sixties--10 to 12 years after that scene was set. The guy's hairstyle looks wrong for that period, too.
Well, Moe Greene was "a man of vision." He probably saw the trends coming and clued in his men.
