The original jatha included Bhai Maninder Singh Ji & Bhai Jatinder Pal Singh (Sri Nagar wale). They had been performing kirtan from a very young age and were self-taught. Bhai Harjinder Singh is the elder brother of Bhai Maninder Singh who are both exceptional vocalists and very able harmonium players. Bhai Jatinder Singh played the Tabla with them.
Nowadays, Bhai Harjinder Singh performs with his son and resides in India. He has been honored by the Akaal Takht with the title of "Panthic Shiromani" along with Bhai Pinderpal Singh.
