Back in March, he announced the onset of dementia and also noted that his arthritis made playing the guitar a struggle. The one-time teen idol starred alongside Shirley Jones, Susan Dey, and Danny Bonaduce on The Partridge Family on ABC.

The show spawned several radio favorite songs, such as: I Think I Love You, Cherish, and the TV show's theme song, Come On Get Happy.

At a London concert in 1974, some 800 people were injured at a Cassidy concert, leading to the death of a teenage girl days later. Cassidy had a hit with I Write the Songs before Barry Manilow adopted it.

The son of the Tony-winning Jack Cassidy, David Cassidy is survived by half-brothers Shaun, Patrick, and Ryan Cassidy, a daughter, Katie, and son, Beau Cassidy.
