Latest in Kochadaiyaan is that superstar Rajini has rendered a song in Rahman's music. It's also learnt from reliable sources that the song was recorded recently in Rahman's composition. Not falling into the conventional boundaries of a song, this will be more like a verse type song, much along the lines of 'Thendralodu Udan Pirnadal' from the movie Raja Raja Cholan sung by Sivaji Ganesan.
The last time Rajini rendered a song was for P Vasu's Mannan, a little more than a decade ago. It was a duet with S Janaki called 'Mullai Poongodi'.
