Some songs are timeless. Subrahmanya Bharati's villinai otta puruvamazhai tannai vElavA is one such for me. It is easy to listen to MSS's version of it over and over. Despite having learnt it, I am still trying to identify the name of the rAgam.
It appears to have the ArOhaNam and avarOhaNam of a kAkaLi niSAdam version of suDhaDhanyAsi along with chatuSruti dhaivatam in its avarOhaNam.
