Liz has a camera as Marie Osmond (pictured on top) performs in the opening called "The Loft." Wanda fails to come in, but introduces to B.J. Thomas. Ashley (Jessica Walter) had the opening intro of the 100th anniversary of Walkerville, as Marie introduces to the jam, especially Ricky Skaggs, who refuses to sing "Same Ol Love" due to time constraints, but performs "Heartbroke." Sammy Kershaw sings Mel Street's "Loving on Back Streets" after Wanda asked Ms. Frizzle a question. Carl Perkins wrote "S-W-A-D-E," but Wanda insisted it was "S-U-E-D-E." The kids went to the zoo as Timmy Cappello performs. Harry (Michael York) built Liz's habitat as Phoebe introduces to Sammy Kershaw, but he calls her a wrong name (same as episode 10). Ashley and Arnold were talking before he introduces to Carl Perkins. Keesha has a video tape to make the ants in this very last scene.
