Say Hello To- ANN THOMAS—a sweet-faced young miss of 23 who is radio’s expert in tough-gal roles. You hear her tonight as the thick-witted maid, Lily, in Meet Mr. Meek over CBS —and other days when you tune in a particularly tough feminine voice, the chances are that’s Ann too. She’s a veteran of same 35 productions on Broadway , and long since lost count of all her microphone characterizations. Her big-guest thrill recently came when Minerva Pious, Fred Allen ’s dependable comedy actress, had to go to Hollywood for two weeks and Ann was chosen to handle her roles on the Allen program. She’s blonde, New York born, and single.
