An associate choreographer who worked on Michael Jackson's planned series of comeback concerts has told a jury in the United States she never saw signs the singer was ill or might die.
Stacy Walker is testifying for AEG Live LLC, the promoter of Jackson's This Is It shows planned for 2009.
She says that while she was frustrated the singer missed numerous rehearsals, she was convinced after seeing his final preparations that he could perform 50 shows in London.
Jackson's mother, Katherine Jackson, is suing AEG, claiming it did not properly investigate the doctor convicted of involuntary manslaughter for her son's death.
Ms Walker told jurors in Los Angeles it was not her job to focus on Jackson or his health, but that the singer appeared happy about the shows.
Witnesses for Katherine Jackson have testified that the singer was poorly during rehearsals.
