Helen Kane Adopted Baby Esther's Boops to Further Her Own Popularity (1934)

Another witness, who insisted that Helen Kane's "Boops" were not 100 percent novelties, was Marion Luber, a dancer, who told the court that early in 1928 she heard Baby Esther a Negro child performer employ the "Boop" style of singing which Miss Kane considers her own. 

Under cross-examination this witness said she did not recall the songs she heard Bay Esther sing, but that she remembered the child's songs were replete with "Boops" and "Doops."

Testimony was offered at yesterday's session of court to convey the impression that Miss Kane adopted Baby Esther's "Boops" to further her own popularity as a singer.
