Tune I heard from Bhai Dilbagh Singh and Gulbagh Singh's rendition of "Mehrvan Sahib Mehrvan" -- lovely composition -- Not sure if it's original or not though.
This is what I remember of it + improvisation:
I was actually trying to record Gorakh Kalyaan (see old posts saying "Rageshri Without Ga") . But I couldn't play it the way Ustad Rashid Khan sings it in the recording I have.
So I switched to this instead.
Supposed to be Choti Tintaal &/or Kaherva ..
Was focused on the embellishments etc so didn't pay attention to timing.
