On The Gist, our regular guest Chris Molanphy returns to explore the "psychedelic-lite" and "semi-baroque" Billboard chart hits from 1967. He'll explain how the music industry took a druggy cultural movement like the "summer of love" and made it palatable for a mainstream audience. For the Spiel, don't be a Peru, the first meaning. All will be explained in the Lobstar of the Antentwig. Do check out this Spotify playlist to hear the songs mentioned in today's show one more time. Penny Lane and Ruby Tuesday will both be there.
