Not listening to anything right now but have been binge watching the TV series Gunsmoke which ran for 20 seasons (1955-1975). I'm currently half-way thru season 7. Unlike the TV series of today with their paltry 12-13 episodes per season, Gunsmoke had 39 episodes per season. For the first 6 seasons it was a 30 minute show but switched to a 60 minute show in season 7.
