"Life is not a dress rehearsal," Toni Grant, one of the early voices in radio psychology, told listeners. Jill Leovy Contact Reporter Toni Grant, a Los Angeles-based radio psychologist who reminded listeners in the 1980s that "life is not a dress rehearsal" and inspired a movie called "Choose Me," died March 27 in Beverly Hills, said her daughter Kimberly Warneke. She was 73. The cause was not disclosed. Grant was among the early voices in radio psychology. Her on-air debut in 1975 on the KABC-AM graveyard shift followed the path blazed by Dr. Joyce Brothers, who was already a household name by then. Grant said she was inspired by a show on a San Francisco radio station then seeking to capitalize on the popularity of airwave therapy. Her L.A. version of the call-in genre quickly moved to prime time, and by 1981, it was nationally syndicated, reaching more than 180 stations at its peak. On her KABC show, which later moved to KFI-AM, Grant tackled social issues of the day, such as the proliferation of divorce and the shifting dating scene. Her advice to troubled callers was sometimes controversial but won her a large following. Critics labeled her anti-feminist for her criticisms of uncommitted intimacy and her emphasis on the importance of femininity and charm for women.
