Rumored to be losing stars to Paul McCartney's Concert for New York City on Saturday night, Michael Jackson nonetheless attracted quite a lineup for his United We Stand: What More Can I Give charity concert at RFK Stadium in Washington on Sunday. Lasting 11 hours and plagued by technical problems and boos, according to the Washington Post, the charity benefit left the 47,000 ticket buyers in a foul mood by the time Jackson appeared around midnight. "Don't do it because I'm asking you, but because it's the right thing to do," said Jackson, making an appeal for donations before launching into "Man in the Mirror." Premier boy band Backstreet Boys opened the show with "The Star Spangled Banner," and continued through several of their chart-topping songs, dedicating one to a member of their road crew who died in one of the airliners that crashed into the World Trade Center. "It's a privilege to be here today to salute al of the heroes," said Backstreeter A.J. McLean. James Brown turned in a typically idiosyncratic set, going from "Sex Machine" to "God Bless America" to "Killing is Out, School is In." Also appearing: Aerosmith, Carole King, Al Green, Pink, P. Diddy, Huey Lewis and the News, and Rod Stewart. Proceeds go to the American Red Cross Liberty Fund, the Salvation Army Relief Fund, and the Pentagon Relief Fund.
