This episode marked the first on-screen performance by the Partridges singing "I Think I Love You". In episode 8 "But the Memory Lingers On", the song was played over the opening picnic scene.
That song went on to become a number-one hit on the Billboard singles chart (& worldwide) and wound up selling over 4 million copies.
If you look closely at Tina's house, you might notice that it looks awfully familiar. That's because it was the former home of Darrin and Samantha Stephen's on "Bewitched".
This episode had a reunion connection. Leonard Stone & Dave Madden were also on "Camp Runamuck".
Leonard's better known as Sam Beauregarde from "Willy Wonka & The Chocolate Factory".
