I read somewhere that Groucho Marx had trouble getting a radio show, (This was pre- You Bet Your Life.) After hearing him guest on an episode or two, (NOT his Jack Benny appearances notably,) I can see why. He did not seem funny at all. I attributed this to writers wanting to write Marx Brothers comedy material, and not being a Marx. Groucho never seemed comfortable with scripted lines live on the air. (Hmm, maybe he WAS related to Mary after all!) Even in Flywheel, Shyster, and Flywheel--which was taken largely from their vaudeville act and movies-- his delivery and timing seemed off. But when you listen to You Bet Your Life, he is in his element: Live, off the cuff humor that shows that he is an incredibly sharp guy.
Groucho managed to get a number of radio shows, but none of them lasted very long until You Bet Your Life. I'm quoting this from memory, and it's been described in detail in books by Groucho and by his son Arthur, but in a nutshell, Groucho had been invited to do a gig on a Walgreen Drugs special, at a time when he had lost another show. Feeling sorry for himself, he had to sit around, cooking his heels, until he was to go on midway through the show, which was running late.
In the script, Bob Hope was supposed to be running a radio station in the middle of the Sahara Desert. When Groucho's turn came to go on, Bob Hope delivered the scripted line, "Groucho Marx, what are you doing in the middle of the Sahara Desert?" Groucho departed from the script and said, "Desert hell, I've been standing in a drafty corridor for a half hour." Bob Hope dropped the script, too, and the two of them ad-libbed hillariously for several minutes. Fortunately, the show was pre-recorded, since some of the remarks were certainly not fit for broadcast in the 1940s.
As it happened, John Guidel was in the audience. He went backstage to talk to Groucho, suggesting that the reason Groucho hadn't succeeded in radio was that he needed a show that allowed him to ad-lib. Groucho was skeptical of a quiz show format, but he realized he hadn't succeeded with anything else, and John Guidel had been quite successful with Art Linkletter. And so, You Bet Your Life was born, and the rest is history.[/quote]
