On the series[]
In What? And Get Out of Show Business?, Keith Partridge plays the song around the house until Shirley Partridge has involuntarily memorized it. The song is originally written with Gloria Steineman's vocals in mind, but after Gloria comes down with the mumps, the Partridge kids talk Shirley into singing her part. Danny Partridge uses the song to convince Reuben Kincaid to manage them. It's the first of their songs to get airplay. The family plays it at Caesar's Palace. It takes them a minute to get started because the kids are paralyzed by stage fright.
