Aniruddha Knight did Abhinaya for it at his performance last month. Unnikrishnan sang it at his Kalakshetra performance. Sorry, I couldn't any audio link. The composer is Dharmapuri Subbarayar.
As far as I know D.Subbaraya Iyer has not composed any varNAs. Maybe some more caraNAs are missing here. If I had access to Unnikrishnan's rendition I can confirm the words.
