Under cross examination
.... Payne acknowledged that some of Jackson's behavior, including grogginess, lethargy, insomnia and occasional paranoia, were possible symptoms of prescription drug abuse. He also said that despite testifying earlier that he worked with Jackson one-on-one five days a week, he couldn't recall how many rehearsals the singer actually attended.
Payne was working for AEG and said he relayed his concerns about Jackson's possible prescription drug use to tour director Kenny Ortega. Jackson was struggling to get into shape for the shows, and Payne said his voice coach suggested using a voice track for fast-paced songs until the singer's stamina improved.
He said Jackson wanted to use a teleprompter during the shows as "extra security," but it was an aid the performer had not used in his two previous tours.
