I want to know the answer to the following question:
What does the Lord Mayor's Show parade commemorate and celebrate?
All the background I'm provided with is that "Traditional parades include November's Lord Mayor's Show, a centuries-old event celebrating the annual appointment of a new Lord Mayor of the City of London with a procession along the streets of the City, and June's Trooping the Colour, a formal military pageant performed by regiments of the Commonwealth and British armies to celebrate the Queen's Official Birthday.". Is that enough to answer the question?
Answer: yes
