Which Irving Berlin classic does Princess Margaret sing with President Johnson during her White House visit in season 3?

While Margaret's White House visit did really occur and was reportedly quite a party, the show's creators employed some dramatic license — allowing for some of the best zingers of the series. Margaret: “You spent three years as vice president. I’ve spent my whole life as vice queen.” LBJ: "Jack Kennedy would’ve killed his own mother just to take the skin off her ass to make a drum to beat his own praises."
