Ron Brownstein, Senior Editor at Atlantic Magazine and Senior Political Analyst for CNN, has written a book about how 1974 was a watershed year for culture and politics in Los Angeles. --Wait!! Don and John were living and working in L.A. in 1974!  Coincidence? I think not!

Head on down to your local Wawa for a hoagie and some wooder ice, as John and Don talk with former Philadelphia Inquirer TV critic Ellen Gray.  They'll be discussing all the Philadelphia quirks and references in the HBO murder mystery "Mare of Easttown." It's more fun than a vegan cheesesteak!

John and Don are huge baseball fans, and so is Sweeny Murti of WFAN Radio and the New York Yankees. Listen in as Sweeny tells the Innertube boys about his hour with Billy Crystal, Tom Jane, and Barry Pepper, the boys of 61*.

John and Don re-unite with Art Caplan, the Mitty Professor of Bioethics at New York University Langone Medical Center, to get the hows and whys of vaccine hesitancy and herd immunity. But, unfortunately, no Bill Gates divorce jokes.  Darn!

(Please hum Star Trek theme) Bruce Betts, Chief Scientist of the Planetary Society, takes John and Don where no Musical Innertube has gone before (except maybe our first episode with Mat Kaplan)! To Mars!  In an airplane!

Don and John talk with Julie McKelvey, who's climbing the seven highest mountains in the world! She's doing it for a sense of accomplishment AND for a good cause. SPOILER: if you'd like to pledge as Julie climbs Denali, go here: https://pledge.giftofsound.org/summitforsounddenali

Making a return appearance to the Musical Innertube is educator Abby Mahone, who, along with fellow educator Courtney Hart, tells Don and John how students, teachers and parents in their school are coping with COVID.

Don and John talk to old friend Mike Hingson, who is many things:  author, motivational speaker, and someone who survived the collapse of the World Trade Center on September 11th of 2001 by walking down the stairs from the 78th floor with the help of his guide dog Roselle.

What can a city's architecture tell us about its health and growth? John and Don find out by talking with the Philadelphia Inquirer's Pulitzer Prize-winning architecture critic Inga Saffron, who talks about her city and trends in general.

Finish off 2020 with John and Don and bio-ethicist Art Caplan, who, like all of us, wants the pandemic to be over -- he's just not optimistic about that happening right away.
