Shirley Jones

David said, "At the auditions, they introduced me to the lead actress (Shirley Jones) 'cause they had no idea, they had no idea. So I said, 'What are you doing here?' She looked at me and said, 'What are you doing here?' And I said, 'Well, I'm reading for the lead guy.' I said, 'What are you doing here?' She said, 'I'm the mother!'" Cassidy discussed his relationship with his stepmother on the show: "She wasn't my mother, and I can be very open, and we can speak, and we became very close friends. She was a very good role model for me, watching the way, you know, she dealt with people on the set, and watching people revere her." After the show's cancellation, Cassidy remained very close to his half-brothers and the rest of his Partridge Family cast mates, especially Shirley.

Cassidy appeared on many shows alongside his stepmother, including A&E Biography, TV Land Confidential, and The Today Show, and he was one of the presenters of his stepmother's Intimate Portrait on Lifetime Television and the defunct reality show In Search of the Partridge Family, where he served as co-executive producer. The rest of the cast also celebrated the 25th, 30th, and the 35th anniversaries of The Partridge Family (although Cassidy was unavailable to attend the 25th anniversary in 1995 owing to other commitments).
