Laurie looks at the sign that says the Temptations SAT (as in playing on Saturday) and states that they were "just here", implying that it's after Saturday. Yet when the brothers are discussing the booking a few minutes later, they question if the Partridge Family will be working for them "this weekend" (implying that the weekend is approaching or nigh upon them) and then state that they're expecting the Temptations, indicating that the sign is for a forthcoming show. Surely Laurie has been around the gig biz long enough to know that venues don't leave past gigs on their signboards when they're promoting a forthcoming show.
