Ustad Amir Khan used to sing a wide variety of Kalyan Ragas including :-
Ram Kalyan / Priya Kalyan
Shuddha Kalyan
Yaman Kalyan
Hindol Kalyan
Puriya Kalyan
Anandi Kalyan, etc
This is yet another variant of Kalyan - Raag Maru Kalyan. The drut bandish "Kahe Karat Gumaan" is indeed a wonderful composition of him.
