Hence the central role of St. Paul's Cathedral, the Bird Lady, and the lyrics of the classic song "Feed the Birds" - which was known to be Walt Disney's favorite of all time.
All around the cathedral the saints and apostles
Look down as she sells her wares
Although you can't see it,
You know they are smiling
Each time someone shows that he cares
I have not read the original novel by PL Travers, but I get the sense the writing is in keeping with the spirit of earlier peers like Charles Dickens and the morality behind "A Christmas Carol."
