I want to know the answer to the following question:
How many people in London attended each day of the the three day event?
All the background I'm provided with is that "She again undertook an extensive tour of her realms, which began in Jamaica in February, where she called the farewell banquet "memorable" after a power cut plunged the King's House, the official residence of the governor-general, into darkness.". Is that enough to answer the question?
