Say Hello To- BILL PERRY—the tenor star of CBS’ Saturday Night Serenade, who started his career in Vanderbilt University by singing and playing the trombone in a band to earn money for tuition fees. After singing on a local station in Tennessee, he came to New York and made his network debut in 1933. Now he’s in his sixth year as star of the Saturday Night Serenade, and has missed only one broadcast. Bill is athletic, nearly six feet tall. His list of favorite recreations includes almost every type of rugged sport, and he attends every prizefight he can. His ambition is to be a concert singer like JohnCharles Thomas , but he dreads the thought of singing a season or two in the Metropolitan Opera , which would be necessary to reach that goal.
