Mariah Carey gives opening performance at Michael Jackson's LA memorial

Mariah Carey gave the opening performance at Michael Jackson's Los Angeles memorial on Tuesday, with a rendition of the Jackson 5's ballad "I'll Be There." The duet with Trey Lorenz began after Jackson's golden casket was placed in front of the Staples Center stage while a church choir sang. The public event came after a private service for family and friends in a cemetery hall in the Hollywood Hills. Jackson's flower-draped casket was brought to Staples Center in a motorcade under law enforcement escort.
