During the 1940s, whenever Hollywood celebrities with vocal talents attended parties, they were expected to perform songs. In 1944, Loesser wrote “Baby, It’s Cold Outside” to sing with his wife, Lynn Garland, at their housewarming party in New York City at the Navarro Hotel. They sang the song to indicate to guests that it was time to leave. Garland has written that after the first performance, “We became instant parlor room stars. We got invited to all the best parties for years on the basis of ‘Baby.’ It was our ticket to caviar and truffles. Parties were built around our being the closing act.”
