Funny you should say that. Jack Gould, the critic for The New York Times, said in his review of the show's premiere that it was "good enough to make one wish he could have seen it."
Since it sounds as though you've never heard it, here's the premiere edition of The Big Show. The cast: Fred Allen, Mindy Carson (pop singer of the day), Jimmy Durante, Jose Ferrer, Portland Hoffa, Frankie Laine, Paul Lukas, Ethel Merman, Russell Nipe, Danny Thomas, Meredith Willson (who was also the show's musical director), and, of course, Dame Tallulah. Not to mention Fred Allen (who appears in the show's final third) first delivering the anti-television crack most associated with him (often attributed, erroneously, to Ernie Kovacs) . . .
'Preciate it! Though I took the usual Radio-TV courses in journalism school, and my uncle taught radio advertising, giving me access to swell archive files of old shows on which Coca-Cola and Texico commercials aired, I'd not heard it before. Thanks again!
