You suppose a small piece of a devotional song --- janki nath sahay kare to kaun bigad kare nar tero ---used in Hindi film gangajal starring ajay devgan gracy singh is sung by pandit ajoy chakraborty?

That piece is sung by the noted and renound saragi player, Ustad sultan khan. the original recording was done by DV Paluskar and a newer rendition by Pandit ajoy chakraborty in an album "ishwar Allah tere naam"
