Is there any mention of London in the story of Sai Baba in Chapter 36?

Based on the provided text from Chapter 36 of the Shri Sai Satcharitra, there is no mention of London. The text does, however, state that people from both within the country and from abroad worshiped Sai Baba, noting that "the flag of his devotion flutters" in these places. While it confirms his international following, it does not specify any particular cities or countries like London. The chapter instead begins to narrate a story concerning "Two gentlemen from Goa" who came for Sai's darshan. Therefore, your query about London cannot be substantiated from this part of the text.
