Who were the devotees from Madras mentioned in Chapter 29, and what was their experience in Shirdi?

Chapter 29 describes a group of devotees from the Madras region who came to Shirdi for Sai Baba's darshan. Their fame had spread as they were engaged in devotional singing. They were on a larger pilgrimage to Kashi and stopped at Shirdi along the way. This group belonged to the Ramdasi sect and performed their devotional singing with great enthusiasm. Upon meeting Baba and taking his darshan, they attained peace and stayed near him for several days. As a sign of his pleasure, Baba gave them eight rupees and eight annas, though the text also notes his unpredictable nature in giving.
