Let me, however, throw in a possible extra special pleading for Welles, in this case. If we remember how careless Welles was about rehearsals for radio shows in his long experience, it is possibe that he had not read that line, written by someone else, until he got on the air.
Yes, that is certainly a possibility. If that's the case, I would have loved to have heard what Welles said to his writers after the show.
