At 14, Renee Olstead, who costars on the CBS sitcom Still Standing, isn't vying to be the next teen-pop queen. Instead, she sings jazzy standards that her grandparents could listen to. And, for a girl too young to have seen the inside of a cabaret club, she's remarkably convincing as a torchy chanteuse. Olstead displays a natural swing and sophistication, along the way evoking Rosemary Clooney (on "On a Slow Boat to China"), Dinah Washington (on "What a Difference a Day Makes") and Doris Day (on "Sentimental Journey"). Although some of these numbers, such as "Summertime," have been done to death, Olstead is really someone to get jazzed about.
