DENIED: Warner Bros. is saying that reports in a British tabloid that a London schoolboy, Joe Sowerbutts (now there's a name), was hired to dub two scenes for 12-year-old star Daniel Radcliffe in "Harry Potter and the Sorcerer's Stone," because Radcliffe's voice was changing on account of puberty, are just not true. "No voice other than that of Daniel Radcliffe was used to portray Harry Potter in the film," said a statement released on behalf of producer David Heyman, and director Christopher Columbus. Sowerbutts said that he spent one day recording at Shepperton Studios, near London. He does, however, reportedly provide the boy wizard's voice on Nintendo and PlayStation Harry Potter games . . . EARNED: Last weekend's all-star "The Concert for New York City," with Paul McCartney, Mick Jagger, Elton John and others, has raised more than $30 million for World Trade Center relief efforts, and donations are still being accepted. The running total as of Thursday includes money raised from ticket sales, corporate sponsorships, TV rights, merchandise sales, and donations made through a toll-free number and the Internet . . . SWITCHED: Geraldo Rivera, 58, is quitting his prime-time CNBC talk show (and $4 million a year contract) to become a war correspondent for Fox News Channel, saying Thursday he couldn't bear to stay on the sidelines during a big story. Rivera's last CNBC show after seven years will be on Nov. 16. He said he'll be leaving for Afghanistan the next day . . . CLEARED: More than three centuries after they were accused, tried and hanged as unrepentant witches on Gallows Hill in Salem, Mass., five women have been officially, posthumously exonerated by the state, reports Friday's New York Times. The act was signed on Halloween and cheered up the descendants of Bridget Bishop, Susannah Martin, Alice Parker, Wilmot Redd and Margaret Scott, all put to death in 1692. Way to go, girls.
