 Frank Morgan (I) (qv) supposedly does voice imitations of  Al Jolson (qv), Ted Lewis (I) (qv), Wallace Beery (qv),  Robert Taylor (I) (qv), Mickey Rooney (I) (qv) and  Hedy Lamarr (qv). However, Rooneys and Lamarrs voices were  dubbed by other actors, and Taylors voice was so perfect it was  probably from the soundtrack of one of his films or the actor  himself. Morgan also impersonates Clark Gable (qv),  Claudette Colbert (qv) and Spencer Tracy (qv) in a scene from  _Boom Town (1940)_ (qv) which opened 3 months earlier. Again, the  voices were so perfect they undoubtedly came from the soundtrack of  that movie.
