Yes he played right up until the day before he passed, I believe. This is probably one of his last performances ever :( I was only one month old when this was shot but I still feel so connected to his music!
Marwa is al late afternoon Raga which is very melodious one and Pandit Nikhil Banerjee has played it superbly to portray its real beuaty which is apparently very difficult for an Artiste to do so. Ut Amir Khan had rendered his vocal music on this Raga which is one of his best performances.
This recording was fully video recorded , some of the clippings have been already shown in Steven Viegel's documentary. Was waiting for the full version. Thank you
