Dhanush to pen a song for Kaththi?

Kaththi directed by AR Murugadoss has Vijay and Samantha in the lead roles. The film has been progressing well with more than 50% of the shoot completed already. It is also reported that the film will have Ilayathalapathy performing seven gritty stunt scenes. The album has six tracks in total and is composed by Anirudh. The grapevine in K’town is rife that Dhanush, who shares a great rapport with Anirudh, is expected to pen a song for the film. It would be interesting to see if Vijay croons for Dhanush set to the tunes of Anirudh.

The young composer has already finished four songs for the film. Vijay has already praised Anirudh after listening to the third song in the album. How awesome would it be to see the Anirudh-Vijay-Dhanush trio coming together for a song?
