"Baby, It's Cold Outside" is a Christmas song with words and music by Frank Loesser. Loesser wrote the duet in 1944 and premiered the song with his wife, Lynn Garland, at their Navarro Hotel housewarming party, and performed it toward the end of the evening, signifying to guests that it was nearly time to end the party. Lynn considered it "their song" and was furious when Loesser sold the song to MGM. It is a call and response duet in which one of the singers (usually performed by a male voice) attempts to convince a guest (usually performed by a female voice) that they should stay together for a romantic evening because the weather is cold and the trip home would be difficult. Originally recorded for the film Neptune's Daughter, it has been recorded by a number of artists since its origin
