Audio problem: In the final song, "This is What It's Like to Be Lovers", the lead male studio singer starts the song, not David Cassidy, then they switch to David Cassidy's real voice halfway through for just two lines, then they switch back to the male voice of the studio singer.
The Partridge Family (1970)
1 audio problem in season 1
Starring: Shirley Jones, David Cassidy, Danny Bonaduce, Susan Dey
Princess and the Partridge - S3-E3
Continuity mistake: Keep an eye on the woman seated behind the Princess at the concert. In some shots she is wearing a necklace and seated beside a younger man; in others, she has no necklace and is seated beside an older man. (00:21:55)
Shirley Renfrew Partridge: There's no sense in waiting up. Laurie's in good hands.
Danny: That's what I'm afraid of.
Keith: ...I wouldn't worry about him. He's an archaeologist. He can always dig up a girl.
Trivia: Danny is humming show tunes. Keith sarcastically asks "What's next? Oklahoma?" Shirley Jones, who played Shirley Partridge on the show, was in the movie "Oklahoma!" (00:07:30)
