Ladies And Gentlemen We Present The Lord Mayor Of London and The Duchess Of London Walks!

This from London Walks guide Jean… 
"On my Dickens Christmas Carol Walk on Christmas Eve, I'd just got to the bit about "The Lord Mayor in the stronghold of the mighty Mansion House gave orders to his fifty cooks and butlers to keep Christmas as a Lord Mayor's household should....." when who should appear but the Lord Mayor himself. He said he wished he had fifty cooks and butlers, and greeted the walkers. Though you might like the picture. Best wishes, Jean."
