Charlie and Marv have been assigned to put on a show about the planets and perform music. Charlie has been practicing on his clarinet, while Marv can use his keyboard to create all sorts of neat noises. Lola wants to join in too, but she doesn't know how to play an instrument and she wasn't selected. Charlie tells her that he's sure there'll be a time when she's selected for her class, but Lola wants to play music now. Then, Charlie gets a bright idea as to how she might be able to play some music.
