While I was listening to the radio today, I heard a promo for this week's edition of Only A Game that mentioned that they'd be discussing Babe Ruth's 1934 Tour of Japan. I turned to my daughter and said "Hey, I know the guy they're going to be talking to!" I got an email from Rob later on confirming that he was going to be on the show.
You can check here for when your local NPR station might be running the show. It's also broadcast on the SiriusXM public radio channel as well as being available as a podcast.
