​This was our Christmas card greeting, 2021.  
Baby, It's Cold Outside, by Frank Loesser, 1944.
In the bio of her dad written by Frank Loesser's daughter, Susan Loesser:  
A Most Remarkable Fella:  Frank Loesser and the Guys and Dolls in His Life....
she describes how at the Hollywood parties her parents attended,
they would always do this much-loved number as the closer.
