How Little We Know

"How Little We Know" is a song written by Hoagy Carmichael and Johnny Mercer for the 1944 film To Have and Have Not, where it is performed by the character "Slim" played by Lauren Bacall. A young Andy Williams recorded the song for the film as a possible alternative track to dub Bacall's low voice; however, Bacall claimed that they used her singing.{{cite web|title=When Andy Williams dubbed Lauren Bacall|url=https://www.latimes.com/entertainment/movies/la-xpm-2012-sep-26-la-et-mn-andy-williams-movie-lauren-bacall-20120926-story.html|work=Los Angeles Times|date=26 September 2012 }} After the film's release, it was a hit recording sung by Judy Johnson. Nick Perito and his orchestra recorded an instrumental cover of the song for Muzak's Stimulus Progression program in the 1970s.
