Mister Rogers' Neighborhood (1968) : 8x9

Mister Rogers arrives with a chromaharp (autoharp) and shows how it is played as he sings Old MacDonald. He shows a picture of a standing harp in a book. At Brockett's Bakery, Mister Rogers compares the size of his chromaharp with a large harp in the bakery's soda shop. Chef Brockett arrives with Edward Druzinsky who plays the harp. Returning to his house, Mister Rogers finds a note from the Gordons who had stopped by to see him and gone to his home to look for him. Calling his wife, he asks her to send the Gordons back to the television house. In the Neighborhood of Make-Believe, Handyman Negri and Daniel Striped Tiger are trying out various musical instruments as they wait for the Platypus family to return from Westwood.
