The entire episode is filmed on long shots.
The variation on "Twinkle Twinkle, Little Star" that Rodrigo plays on the violin is from Mozart's "Twelve Variations on 'Ah! vous dirai-je, Maman,'" originally composed for solo piano. The French folk song quoted in the title is sung to the same melody as "Twinkle, Twinkle," and predates the English lyrics.
