Mister Rogers Talks to Parents About Discipline

Mister Rogers arrives with a piano roll for a player piano. He explains how a piano roll works and talks briefly about how he had to practice regularly to learn to play the piano. At Negri's Music Shop, Joe Negri helps Mister Rogers to demonstrate a player piano before they look inside to see how it works. Before Mister Rogers leaves, Mr. Negri shows a short film about how piano rolls are made.
