Cassidy's racing passion

David Cassidy has raised thoroughbreds since the 1970s when he rose to fame playing Keith Partridge on The Partridge Family.

The entertainer and former teen idol will share his enthusiasm for the sport when he delivers the keynote address at an induction ceremony for the American National Museum of Racing's Hall of Fame.

"It's one of the highlights of my entire adult life and career to be asked to speak at the induction ceremony," Cassidy said.

Two-time Kentucky Derby winning trainer Nick Zito will enter the Hall of Fame at the ceremony next month.
