I’m very sad to hear about David Cassidy. There were times in the mid-1970s when he would come over to my house and we even started writing a song together. He was a very talented and nice person. Love & Mercy to David and his family.

“RIP David Cassidy” Who my age did not want to look like, sound like, just be him when they were young? I was lucky to get to know the sweet & very funny real David as an adult & I still wanted to be him.
