Kay Lenz, the actress who plays 'Phoebe, (the girl at the party who is attracted to Opie because he's in a band), in real life grew up to marry David Cassidy, the actor who played 'Keith Partridge' on "The Partridge Family."
Kay Lenz is one of the few actresses that appeared on 'The Andy Griffith Show' that would later go on to do a nude scene in a movie. She appeared nude in 'Beezy' and 'The Passage.'
Although they won't have any scenes together, Kay Lenz, who plays Phoebe, will be cast with Ron Howard in "American Graffiti" six years later.
At one point a camera shot shows one of the girls at Arnold's party wearing orange shoes. This is a sign that Mayberry was slowly entering the "Swinging 60s," as conventional black, brown, or white shoes would have been all that was acceptable just a few years earlier.
