Other mistake: The Partridge family is suppose to be famous, but they never seem to play to more than a small handful of people in some lounge.
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: Johanna is played by Cheryl Stoppelmoor - who is today known as Cheryl Ladd.
