Danny Bonaduce says Johnny Cash stepped in on a tense set moment during the pilot for The Partridge Family, telling a 10-year-old Bonaduce he would be fine after David Cassidy corrected him mid-performance. The memory surfaced again on the Thursday, May 28 episode of Pop Culture Retro!, bringing a sharp backstage story from 1970 back into view.
Bonaduce said Cash made a surprise cameo at Caesars Palace in Las Vegas during the pilot and walked onstage to introduce the fictional family band before their performance of “I Think I Love You.” When the curtains opened, he recalled, the cast froze with fear. Then Cassidy stopped the music to correct him, telling him, “You don’t strum a bass guitar, you pluck it. Do you think you can pluck it, kid?”
Cash did not let that pass. Bonaduce said the country star walked up to Cassidy, put a finger to his face and turned to the child actor with a reassurance that cut through the nerves: “You’re going to be fine, kid. You’ll get it.” For Bonaduce, who said he was 10 years old at the time, the moment has lasted far longer than the live performance itself.
The story fits the strange half-real world of The Partridge Family, which debuted on ABC on Sept. 25, 1970 and followed a widowed mother played by Shirley Jones and her musically gifted children as they toured as a family band. The show turned Bonaduce, Cassidy and Susan Dey into teen idols, and Cash’s cameo tied one of TV’s most famous pop acts to one of music’s most recognizable voices.
What remains unclear is how much of that backstage exchange was seen anywhere beyond Bonaduce’s own recollection. But his account leaves little doubt about the moment that mattered to him: a child on a TV set, a young cast under pressure, and Johnny Cash stepping in to back him up before the band ever got to play.
