The huge public service for Michael Jackson at Los Angeles's Staples Center concluded Tuesday afternoon after performances by Stevie Wonder, Mariah Carey, Jennifer Hudson, Usher and John Mayer. Jackson's flower-covered casket sat on stage. Jackson's friend Elizabeth Taylor said she would not attend the service but would mourn privately. Jackson's two wives–Debbie Rowe and Lisa Marie Presley–also did not attend. (Photo: WENN)
