The Plaza Mariachi

The Mariachi only appears at the beginning, where Miguel is shining his shoes and telling the mariachi about his family and their disapproval of music. Feeling sympathy for the boy, the mariachi allows Miguel to play his guitar. However, Miguel never gets the chance because his grandmother, Elena discovers him shining the Mariachi's shoes. She scares him off while beating him with her own shoe, causing the Mariachi to run away in fear.
