Music lovers who like the song "Baby It's Cold Outside" probably like hearing it sung by a particular duo. My first choice would be Ray Charles and Betty Carter. I posted a piece here last year about their performance of the song. That post included a video. (To experience it, click on the 2015 link under Blog Archive in the sidebar of this blog. Then scroll down to my post that's dated Wednesday, February 25, 2015.)
The song itself has been around a long time. Written by Frank Loesser and introduced in the 1949 film Neptune's Daughter, starring Esther Williams and Ricardo Montalban, "Baby It's Cold outside" has been performed by pop and jazz singers on live TV shows since the medium's earliest days. The song has also been recorded by many artists. I'll bet most people reading this post have seen or heard it performed by a number of duos.
In addition to Ray Charles and Betty Carter, I like hearing Lou Rawls and Dianne Reeves sing "Baby It's Cold Outside." I'm sharing their recording of it above. Enjoy!
