'The Town Show' is an improvised comedy show where Mark Chavez and Ryan Beil (CBC's Let's Make A ...) build a fictional town from scratch through riffs, scenes, and interviews with special guests sharing hometown stories. At On Air Fest, they'll be recording an episode live and reuniting with Let's Make A ... co-host and stand-up comedian Maddy Kelly to add her own brand of chaos to the made-up town.
