Tell me about the group of devotees from Madras that visited Shirdi.

Chapter 29 describes a group of devotees from the Madras region (now Chennai) who came to Shirdi for Sai Baba's darshan. Their fame had spread in their home region, and they were on a larger pilgrimage to Kashi, stopping at Shirdi along the way. This group, described as travelers, had spent the year engaged in devotional singing. The text notes that they belonged to the Ramdasi sect and performed their devotional singing with great enthusiasm. Upon taking Baba's darshan, they attained peace and stayed for several days, regularly performing loving devotional singing. Pleased with their devotion, Baba gave them eight rupees and eight annas.
