In his heyday, David Cassidy had it all – a hit TV show, the worship of millions of teenage and pre-teen girls and a number of hit songs. David Cassidy died Tuesday night at the age of 67. A family statement gives few details of his death, other than he’d been suffering organ failure. And earlier this year, David Cassidy revealed he had dementia. The 1970s star also spoke about how he’d like to be remembered.
