In Memoriam: David Cassidy dead at 67 (April 12, 1950 – November 21, 2017). The teenage heartthrob, singer/songwriter and actor Socially Sparked our lives in so many ways. He was best known for his role as Keith Partridge in iconic 1970’s Television series “The Partridge Family.”

According to his publicist Jo-Ann Geffen, Cassidy was in critical condition and suffering from organ failure before his death Tuesday. Earlier this year, the singer/songwriter announced his diagnosis with dementia.

“So very sad to hear of David Cassidy passing away💔 He was always so kind and sweet to me. Our shows were both on Friday nights and deep down I dreamt of being a Partridge. His memory and love will live on in my ❤️forever. Love you David. Prayers to his family” — actress Marsha McCormick (@MoMcCormick7)
