Tell me about the group of devotees from Madras mentioned in the Satcharita. How did Sai Baba interact with them?

Chapter 29 describes a group of devotees from the Madras region (now Chennai) who came for Sai Baba's darshan. This group, who had spent the year in devotional singing, stopped at Shirdi while on a pilgrimage to Kashi. The text also details a specific family of four from this tradition: a man with his mother-in-law, wife, and daughter. As described in verse 12, their tradition was of the Ramdasi sect, and they performed devotional singing with great enthusiasm. In a display of his favor, 'Baba also gave them eight rupees and eight annas, as pleased their minds,' showing a specific instance of his interaction and blessing.
