They looked like the perfect musical family — a widowed mom and her five kids traveling the country in a colorful bus, turning every stop into a concert. The Partridge Family was pure 1970s comfort television.
Behind the smiles, the hits, and the catchy theme song, the show was full of surprises, real-life connections, production mistakes, and private struggles that most viewers never noticed.
Here are the hidden secrets that make the series even more fascinating.
It Was Inspired by a Real Family Band
The show was loosely based on The Cowsills, an actual family pop group that scored hits in the late 1960s. Producers originally considered casting the real Cowsills children. They were ultimately deemed too old and not experienced enough as actors, so a fictional family was created instead.
The concept stayed. A single mother and her musical kids hit the road — and television history was made.
Only Two Cast Members Actually Sang
While the entire family appeared to perform every week, only Shirley Jones and David Cassidy provided real vocals on the records. The rest of the cast lip-synced.
Professional studio singers, including the Ron Hicklin Singers, supplied the rich harmonies and background vocals that gave the Partridge Family albums their polished sound. The illusion was complete on camera — and most fans never knew the difference.
Shirley Jones Was David Cassidy’s Real Stepmother
On screen, Shirley Partridge was Keith’s mother. In real life, Shirley Jones was married to David Cassidy’s father, actor Jack Cassidy. She was his stepmother.
The two already knew each other before filming began. Their real-life relationship added an extra layer of warmth (and occasional complexity) to their on-screen chemistry. Many fans assumed David was Shirley’s biological son, which reportedly caused pain for his birth mother, Evelyn Ward.
The Contract That Almost Kept David Broke
At the height of “Cassidymania,” David Cassidy’s face was everywhere — posters, lunchboxes, magazines, and merchandise. Yet his original contract paid him only about $600 a week and gave him no royalties or control over his image.
His manager later discovered a crucial detail: Cassidy had signed the deal when he was under 21. That legal loophole allowed them to renegotiate for a better salary and a share of the profits. Without it, one of the biggest teen idols of the era would have continued earning relatively little while others cashed in on his fame.
Classic Bloopers Hiding in Plain Sight
In the pilot episode, Shirley Jones accidentally says “all five of us” while referring to the family rehearsing in the garage — forgetting there were six Partridges.
In the Season 1 “skunk” episode, a visible wire can be spotted pulling the animal onto the bus during the picnic scene. The story was inspired by a writer’s real childhood experience with skunks living under his house, but Hollywood wasn’t about to train an actual skunk for the job.
Other small set quirks include a wall that appears through the front door in exterior shots but vanishes inside, and the complete absence of monitors, speakers, or amplifiers for the band’s instruments in most episodes.
Danny Bonaduce Was Even More Chaotic Off-Screen
Danny Partridge’s mischievous energy wasn’t entirely acting. Young Danny Bonaduce was known for disruptive behavior on set. He struggled with dyslexia, which made learning lines difficult (one scene reportedly required 36 takes). At the same time, he possessed a near-photographic memory for everyone else’s dialogue and often corrected co-stars mid-scene.
The cast eventually reached their limit. Shirley Jones once ordered him “upstairs to his room” — forgetting the set had no upstairs and she wasn’t his real mother. On another occasion, the kids convinced Susan Dey to pour milk over his head to cool him down. That prank later inspired a scene on the show (with David Cassidy as the target instead).
Susan Dey’s Secret Crush
Susan Dey, who played Laurie, developed a strong, unrequited crush on David Cassidy. He viewed her more like a sister and often shared stories of his female admirers with her, unaware of how much it hurt. Shirley Jones eventually stepped in and told him to stop.
After the series ended, Dey largely distanced herself from the show and has declined most reunion appearances, a choice that disappointed some of her former co-stars.
Other Surprising Details
- There were two actors who played youngest son Chris Partridge. Jeremy Gelbwaks appeared in Season 1 and was replaced by Brian Forster for the rest of the run. Few viewers noticed or complained.
- Shirley Jones had previously turned down the role of Carol Brady on The Brady Bunch because she didn’t want to play a more traditional, domestic mother.
- Early guest stars included future Charlie’s Angels Farrah Fawcett, Jaclyn Smith, and Cheryl Ladd.
- The fictional band earned a real Grammy nomination for Best New Artist in 1971 (losing to The Carpenters).
The Partridge Family delivered feel-good entertainment every week. Decades later, the stories behind the bus, the songs, and the smiling faces reveal a much richer — and more human — picture. The secrets only make the memories better.
