Kochadaiyaan is bringing out the best from Superstar Rajinikanth in all aspects, one has to say. For, the numero uno actor of Kollywood, who is doing a triple role in the movie, has also turned a singer.

The last time when Rajini crooned was for Mannan. He sang the Adikudhu kuliru... song in the company of S Janaki and the number composed by maestro Ilayaraja went on to become a big hit.

And now, the Thalaivar has sung a classical song in the music of Oscar-Grammy winner A R Rahman, for Kochadiayaan. 'It will be on the lines of Ra... ra... in Chandramukkhi- so classical yet so catchy,' say sources in the know.

Directed by Soundarya R Ashwin, the younger daughter of Rajini, Kochadaiyaan has story, screenplay and dialogues by K S Ravikumar. Shooting is expected to start later this month in London.
