Two years ago music director Anirudh and actor-lyric writer Sivakarthikeyan delivered one of the biggest hit songs from the year called “Kalyaana Vayasu”. The song was from the film “Kolamaavu Kokila (CoCo)” and the film was directed by newcomer Nelson and starred Nayanthara in the lead role. Not only Anirudh’s album was a big hit, but also the film. The black comedy was a very big hit at the box office and everyone is now waiting for Nelson’s second film. The second film is called “DOCTOR” and this time Sivakarthikeyan is playing the role of the protagonist and not only as a lyricist. Anirudh will again compose the music for this film. The Doctor team just released a single announcement for a song and published a video. If you want to know more, watch the video below.
