Dhanush has turned singer again -- this time for Karthik Raja, the eldest son of Ilaiyaraaja, who's the composer of Padaiveeran. The actor-producer-director has sung the final track of the album named Local Sarakka Foreign Sarakka.

The makers thanked Dhanush on social media.

The song is said to be a fun number with lyrics by Priyan. Vijay Yesudas, who stars in the film, has previously worked with Dhanush in Maari. The film is by Dhana, an associate of Mani Ratnam.
