Vishal Dadlani sings for Ko 2

It was only recently that the team of Ko 2 created a buzz by releasing a song from the film which was a tribute to the late Dr APJ Abdul Kalam. Now, the film���s composer Leon James has roped in Vishal Dadlani to sing a song in the film.
Talking about the song, Vaa Vaa Vaa... Vettai Aada, which the team recorded last week in Mumbai, director Sarath says, ���This is a montage song that comes in the film at a crucial juncture.The hero is a reporter in the film and this song plays in the background as he and the heroine get ready for their mission. We did not want a regular voice and so, zeroed in on Vishal Dadlani. The song has a rock base with electronic sounds. Na Muthukumar has written the number.���
