Carly Simon says her stage fright makes the prospect of appearing at the Academy Award ceremonies scary, so she's figured out a better way to claim her Oscar if she wins the award for best song. "I intend to have a look-alike," Simon said on ABC's "Good Morning America" program. "If they think it's the real me, that's even better. Only my hairdresser will know for sure." Simon has been nominated for the song "Let the River Run," from the film "Working Girl." The singer-songwriter said she didn't know who would perform the song at the award ceremonies March 29.
