For millions of people, Eurovision is a cultural institution, and one of the biggest live television events on Earth. But for many Americans, it remains a complete mystery. In this episode, producer Andrew Anderson takes Dallas and Grace on a joyful crash course through the history, music, controversies, and glorious absurdity of the Eurovision Song Contest. Along the way, they discover which music superstars got their start in Eurovision, how receiving “nul points” can ruin or launch a career, and what this competition reveals about Europe itself. Featuring “Doctor Eurovision” Paul Jordan.

In our last episode, we followed composer John Williams from his childhood to his 1970s run with Steven Spielberg and George Lucas. Now, we pick up the story as John enters an era of seemingly impossible success… from Raiders of the Lost Ark to Home Alone, Jurassic Park, Schindler’s List, and beyond. In this episode, we explore how John revived the grand orchestral score, conquered the classical music world, and crafted melodies that millions of people can instantly recognize. Along the way, journalist Tim Greiving reveals the habits, quirks, and creative brilliance of this living legend.

John Williams has written some of the most famous film scores ever, from Star Wars to Indiana Jones to Jurassic Park. But before the blockbuster success, there was a kid growing up around jazz musicians in New York, and a young composer trying to find his voice. In this episode, journalist Tim Greiving takes us through John’s early life and career, from his years as a session player to the meeting with Steven Spielberg that changed everything. Along the way, we unpack the stories behind John’s early iconic scores, including the two-note terror of Jaws, the symphonic world of Star Wars, and the mysteries of Close Encounters of the Third Kind.
