did lauren bacall sing in to have and to have not
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.
