<P> Aggregator Rotten Tomatoes reports 97% approval of To Have or Have Not, with the critical consensus stated as, "With Howard Hawks directing and Bogey and Bacall in front of the cameras, To Have and Have Not benefits from several levels of fine - tuned chemistry--all of which ignite on screen ." </P> <P> Cricket, the piano player in the hotel bar, was played by real - life songwriter and band leader Hoagy Carmichael . In the course of the movie, Cricket and Slim perform "How Little We Know", by Carmichael and Johnny Mercer, and "Am I Blue?", by Harry Akst and Grant Clarke . Cricket and the band also perform "Hong Kong Blues", by Carmichael and Stanley Adams . "The Rhumba Jumps", by Mercer and Carmichael, is performed by the hotel band . Bacall shimmies out at the end of the movie to a faster "How Little We Know". </P> <P> A persistent myth is that a teenage Andy Williams, the future singing star, dubbed the singing for Bacall . According to authoritative sources, including Hawks and Bacall, this was not true . Williams and some female singers were tested to dub for Bacall, because of fears that she lacked the necessary vocal skills . But those fears were overshadowed by the desire to have Bacall do her own singing (perhaps championed by Bogart) despite her less than perfect vocal talent . This myth is disputed in Leonard Maltin's Movie Guide entry for this film, but the myth is propagated in a 1986 episode of MacGyver, entitled "Three for the Road", when the character of a veteran movie asks his wife this particular question, whereupon she answers that Andy Williams, when 14, did dub the voice for Lauren Bacall . </P> <P> To Have and Have Not was adapted as an hour - long radio play for Lux Radio Theater, with Bogart and Bacall reprising their screen roles . It was broadcast on October 14, 1946 . </P>
