LOS ANGELES (AP) — A corporate lawyer for concert giant AEG Live LLC has revised his testimony and now says the tour director of Michael Jackson's ill-fated "This Is It" concerts had a signed contract.

AEG Live General Counsel Shawn Trell told jurors on Tuesday that he had forgotten that Kenny Ortega was working under a signed contract.

Trell testified on Monday that Ortega was working under agreements reached through a series of emails, not a formalized contract.

An attorney for Michael Jackson's mother on Monday compared Ortega's emails to messages between the promoter and the singer's personal physician laying out how he would be compensated.

Trell disputed that the situations of Ortega and Conrad Murray were similar.

Katherine Jackson is suing AEG, claiming it hired Murray without properly investigating him.

AEG denies it hired Murray.
