Bonnie Poe and Margie Hines, winners of Helen Kane imitation contests appeared as defense witnesses. Their voices are used in the soundtracks of the disputed "Betty Boop" films. They were not permitted to state whether they had been instructed, in making the cartoon pictures, to imitate Miss Kane's voice. Over the objection of Samuel Wertz, counsel for Miss Kane, and the insistence of Justice Edward J. McGoldrick. Miss Hines told the court that "Boop-Boop-a-Doop" sounds are called "licks." Lou Bolton, theatrical producer, testified for the defense that Miss Kane heard night club singer Baby Esther Jones interpolate "Boo," "Doo," "Wha-Da-Da" and other "meaningless sounds at the end of each bar of music" in April, 1928. A few weeks later, Bolton testified, Miss Kane first began to use "Boop-Boop-a-Doops" in songs at a theater appearance.
