The couple moved to Los Angeles so that Ms. Hossfeld could attend Loyola Law School and Mr. Thorn could be closer to many of his guests, whom he interviews in the study of the couple’s apartment there. People like Jay-Z, the comedian Eric Idle, the author Nick Hornby, the singer and songwriter Nellie McKay, as well as promising comedians, actors, authors and rappers.

Now “Young America” is carried by 18 public stations and has another loyal following on the podcast version of the show. Mr. Thorn and a college pal, Jordan Morris, are the hosts of another podcast, “Jordan, Jesse GO!” As Mr. Thorn put it: “One of the overarching themes of the show is us becoming adults and coming to terms with what it means to be an adult.”

Last summer Mr. Thorn took what he calls “a huge step in that direction” and proposed marriage.

“I thought, ‘What am I doing not locking this down?’ ” he said. “You know what I mean? It became very clear that there was no reason not to get married. We were grown-ups now.”

Listeners of “Jordan, Jesse GO!” immediately became engaged in the couple’s wedding plans. One suggested catering by In-N-Out Burger, a local chain. “Trampolines!” another proposed. Someone else offered to officiate.

Ms. Hossfeld walled herself off from the discussion. “I don’t listen to ‘Jordan, Jesse GO!’ ” she said. “It’s too personal and intense for me.” Still, she was happy to leave the witty brainstorming to her fiancé’s public.

On that show, Mr. Thorn expressed a keen wish to have miniature donkeys known as “donks” roam about the wedding reception. Ms. Hossfeld was all for it. And the listeners were hugely enthusiastic.
