Where can I find the Abbott and Costello radio broadcast from November 4, 1943?

I am searching for the Abbott and Costello radio broadcast from November 04, 1943 (431104) which was the first broadcast for Lou Costello after leaving the show for a year to recuperate from his illness, and the broadcast that he did after learning just moments before that his infant son had accidentally drowned in the family pool. I can find the November 18, 1943 broadcast (with Mel Blanc as Bugs Bunny and Lucille Ball) but that broadcast is two weeks after the one I'm looking for, not to mention the broadcast from November 11th which is also not turning up anywhere. I've tried OTR and I actually own a disk with over 40 hours of A&C shows, all of which seem to be from the OTR website anyway. I hope that someone can help me locate this particular broadcast because it's the first time that google has let me down, and I really want to hear it for myself, especially if it contains Bud Abbott's words at the end of the broadcast explaining the news and Lou's insistence that the show go on as planned.
