Can you describe the group of devotees from Madras who came to visit Sai Baba?

Chapter 29 details the visit of a group of devotees from the Madras region who were on a pilgrimage to Kashi. This group, who had spent the year engaged in devotional singing, stopped at Shirdi for Sai Baba's darshan. The text notes that they belonged to the Ramdasi sect and performed their devotional singing with great enthusiasm. After taking his darshan and attaining peace, they stayed near Sai for several days. Baba, pleased with them, gave them a gift of eight rupees and eight annas for their devotion.
