Samantha's piano teacher is none other than Jonathan Harris. His role here comes across like a variation on his Lost in Space character. We also see Fritz Feld, who guest starred in three Lost in Space episodes. The novelty of having Harris and Feld together here is more interesting than the episode itself. As the piano teacher, Harris is more impressed with Tabatha than Samantha. Through some kind of spell, little Tabatha plays like a professional. Of course, the whole reason for hiring a piano teacher is because Darren (again) forbids any kind of witchcraft. Funny, this was Season Five, and there hadn't been a single episode where witchcraft wasn't performed. What made this idiot think his word was law? Overall, very predictable, mediocre episode.
