The "Boop-oop-a-doop" trial, in which Helen Kane seeks $250,000 damages from the animated cartoon creators of Betty Boop, became complicated when Lou Bolton testified for the defense. Bolton testified that nine years ago in Chicargo he taught Baby Esther, a negro child under his management to interpolate "do-do-de-do-ho-de-wa-da-de-da" between the bars of music in popular songs. "Will you spell that?" asked a court stenographer, "I can't replied the witness, "Put it down as it sounds," ordered Judge McGoldrick. Bolton said Miss Kane heard Baby Esther's song treatment here in 1928 and shortly afterward began her famous "Booping."
