Can you describe Damu Anna's involvement in the Ram Navami festival as detailed in the source text?

Certainly. Chapter 25 explains that Damu Anna played a very significant role in the annual Ram Navami festival in Shirdi. As a regular vow undertaken with immense love and devotion, he provided one of the two large new flags for the festival's procession. The other flag was from the Nimonkars. The chapter details that the procession would commence from the house of Kondaji Sutara, the carpenter, and proceed with the accompaniment of musical instruments. These long banners were then tied to the two ends of the Masjid, highlighting Damu Anna's public and consistent expression of his faith in Sai Baba.
