Cricket's performance of "Fascinating Rhythym" had been seen twice before. The first time was in the second episode of season four Somewhere There's Music (1962), then it was recycled into the later fourth season episode Shannon Malloy (1962) and finally it was used again here.
This is the only episode in which Connie Stevens and Tina Cole (playing Sunny Day) appeared in together, though they share no scenes. With the former's return from suspension, Cole was clearly no longer needed as a substitute. This was probably her last episode; she did appear in one subsequent episode, "The Sisters," but as Stevens was not in that one, in all likelihood it was filmed prior to her return and aired out of production order.
