Dr.Sakuntala Narasimhan learnt it from Chittoor Subrahmanya Pillai, while a student at the erstwhile Central College of carnatic Music. She remembers it in snatches, but has forgotten parts. The charanam has "Tirupathi pura Venkatesa' and I conjenctured that it must be his song. I think it is Ika evaritho not 'naenevaritho'. Please excuse the mistake. There is no audio anywhere; which is why I am desperately searching it; for its archival value.
