On the series[]
In The Eleven-Year Itch, the Partridge Family plays the song at a public pool, on a stage with pillars but no roof, while sunlight gleams off the water and their equipment. Keith Partridge doesn't play an instrument, but walks around the pool at one point. Richard and Julie Lawrence are in the audience.
