I have met KPA's co - artist, KNA, a few times. KNA usually would attend our family functions ( I am one of KPA's sons - in - law). He was there at my marriage too. He confessed to me that he had not touched the instrument after KPA's death. He took to agriculture.
I also understood from him that Nachiarkoil Raghav Pillai too fell sick, perhaps as a strange coincidence and hardly played tavil afterwards; he passed away within a short sapn of time after KPA's death.
