They promised to change you. They ended up changing all of us. On July 20, 1969 humanity watched as Neil Armstrong stepped foot on the moon. It was the dazzling culmination of a decade of teamwork, a collective global experience unlike anything before or since, a singular moment in which every human being was invited to feel part of something larger than themself. There was however, one man who was left out. This week on Radiolab we explore what it means to be together and - of course - the cassette tapes that changed it. Special thanks to WBUR and the team at City Space for having us and recording this event, all the other folks and venues that hosted us on tour, Sarah Rose Leonard and Lance Gardner at KQED for developing this show with us and Alex Overington for musically bringing it to life.
