In the diner scene, members of Ricky's band are playing customers at the counter. When Alberto comes in, Lucy and Ricky greet him and Ricky escorts him to a "ring side seat" in the middle. In the prior scene, there was someone (the saxophone/clarinet player) in the seat to Alberto's left but when Ricky escorts him over, that seat is now empty. The saxophone player was never seen leaving the diner.
