About Baby It's Cold Outside

"Baby, It's Cold Outside" is a popular song written by Frank Loesser in 1944 and introduced to the public in the 1949 film Neptune's Daughter. While the lyrics make no mention of a holiday, it is popularly regarded as a Christmas song owing to its winter theme. The song was released in eight recordings in 1949 and has been covered numerous times since.

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." In 1948, after years of performing the song, Loesser sold it to MGM for the 1949 romantic comedy Neptune's Daughter. Garland was furious: "I felt as betrayed as if I'd caught him in bed with another woman." The song won the 1949 Academy Award for Best Original Song.

This duet is a conversation between two people, a host (called "Wolf" in the score, usually performed by a male singer) and a guest (called "Mouse", usually performed by a female), in call and response form. Every line in the song features a statement from the guest followed by a response from the host. While both the Wolf and the Mouse want the night to continue, the Mouse says they "ought to say no, no, no, sir" and return home, because of what family and neighbors will think. In the film Neptune's Daughter the song is first performed by Ricardo Montalbán and Esther Williams, then by Betty Garrett and Red Skelton but with a comic parody twist: this time the man wants to leave and the woman is the host and wants him to stay.
