Drama critic Elliot Norton interview Ethel Merman in 1981. IN this excerpt from a 30 minutes program, Ethel talks about Cole Porter. The old, familiar voice belts it out just as always, still going strong after 4 decades and a diadem of stage hits. From her 1930 New York stage debut in “Girl Crazy” to her 1970 tour in a revised version of “Hello, Dolly,: Ethel Merman had brought pleasure and happiness to millions of theatre goers all over America. Miss Merman will be Mr. Norton’s special guest this week and she won’t sing, she’ll talk, about herself, her career and about that wonderfully unique endeavor, Show Biz.
