Please elaborate on the story of Sai Baba's devotees from London that is referenced in Chapter 36.

The premise of your question contains a misunderstanding, as Chapter 36 of the Shri Sai Satcharitra does not reference any story about devotees from London. The text explicitly states that Sai Baba is worshipped by people "in the country and abroad," confirming his fame had spread internationally. However, it offers no specific anecdotes related to London. Instead, the chapter serves as an introduction, highlighting the greatness of saints and Sai's divine nature, before beginning a new narrative concerning "Two gentlemen from Goa." There is no information in these passages to elaborate on a story that does not exist within the source material.
