A group of devotees from Madras is mentioned in Chapter 29. What can you tell me about their visit to Shirdi?

Chapter 29 recounts the story of a group of devotees from the Madras region who came to Shirdi for Sai Baba's darshan. This group, known for their devotional singing, was on a pilgrimage to Kashi and stopped at Shirdi along the way. The text specifies that one particular group consisted of four people from the Ramdasi sect: a man, his mother-in-law, his wife, and his daughter. They performed devotional singing with great enthusiasm, and Baba, pleased with them, gave them eight rupees and eight annas. This visit, as detailed in Chapter 29, illustrates how people were drawn to Shirdi by Baba's fame.
