David Cassidy

Fifty years ago today, a TV show premiered on ABC, about a family that had formed a rock band. It was called "The Partridge Family,: and its star was a young actor-singer named David Cassidy.

In very short order, Cassidy became a full-fledged teen idol. Girls went crazy for him. He sold out concert Halls.

But as he revealed in a 1994 memoir, life was not exactly what it looked like on the outside.
