In the ’70s, the Cassidy brothers were on top of the world. David Cassidy became a household name as the heartthrob lead of The Partridge Family, with hit songs dominating the radio and a TV show that made him the apple of every schoolgirl’s eye. His younger half-brother, Shaun, soon followed suit, shooting to fame as one half of The Hardy Boys and topping the charts with bubblegum pop hits like “Da Doo Ron Ron.”

However, early success often comes with pitfalls, as both brothers faced the pressures of instant stardom, relentless fan attention, and the struggle to balance fame with a normal life. Those challenges would ultimately shape their complicated relationship and leave lasting impacts that Shaun still reflects on today.
