It's always better if you watch the film.
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.
Keen observation TB, but I would offer this (courtesy of Wikipedia) Apparently Turtle necks were originally worn as sportswear, but began to apear as casual wear in the 1920's. They became something of a fashion statement by artists and intellectuals, and apparently during that era people like Noel Coward took to wearing them. By the 1950's they were worn by beatniks and people who considered themselves to be artists, including Hollywood types, so it is conceivable that someone connecetd to the show biz side of Moe's operation could have worn a turtle neck in the mid fifties, but probably not likely. I agree the hair is wrong for that era.
