made ten appearances on The Colgate Comedy Hour, and also appeared on The Roy Rogers Show, The Alan Young Show, All Star Revue, The Donald O'Connor Show, and Father Knows Best. On radio, he was heard on The Enchanted Lady as Buster Beetle, Prince Charming and other characters, the child lead on the popular NBC Radio soap opera Dr. Paul and in 1953 as Tiny Tim in Dickens’ A Christmas Carol on Stars Over Hollywood.
